Miles to Yards Converter

The miles to yards converter is a fast, exact length-conversion tool that moves a measurement between the imperial statute mile and the imperial yard in both directions. Type a number in either field and the other updates live, with no rounding ambiguity and no measurement uncertainty, because the relationship between the two units is fixed by international definition rather than measured. It is built for everyday situations where you are handed a figure in one unit and need the reading in the other: a 26.2-mile marathon that a US club advertises in yards, a 100-yard American football field a broadcast needs in metres, a 6 800-yard golf course a travel website wants in miles, a 65-yard cricket boundary, a 1-mile dog-walking route a map app displays in yards, or a 3-mile training loop a coach describes in yards to a runner who thinks in metres. The page also includes bonus read-outs for the same distance in feet, metres, and kilometres.

The converter assumes the modern international statute mile, exactly 1 760 international yards since 1 July 1959. Before that date the United States, the United Kingdom, Canada, Australia, New Zealand, and South Africa each used slightly different yards and miles inherited from older Imperial standards, and conversions between national yards could differ by a few parts per million. The international yard and pound agreement of 1959 unified those values: the international yard was defined as exactly 0.9144 metres, and the international mile as exactly 1 760 yards = 1 609.344 metres exactly. Today every legally defined mile and yard in commerce, science, sport, and engineering equals exactly 1 760 yd, exactly 0.9144 m, and exactly 1 609.344 m.

How to use this converter

1. Type the numeric value you want to convert into the Miles (mi) field or the Yards (yd) field. Decimal values are accepted, including sub-mile values such as 0.25 mi and sub-yard values such as 50 yd.
2. For the Miles To Yards, The opposite field updates automatically as you type. For the Miles To Yards, The update is recomputed on every keystroke, so the panel always reflects the latest value.
3. Read the Result in miles and Result in yards rows to see both sides of the conversion together, for example 1 mi = 1760.000000 yd.
4. Read the bonus read-out strip below the result to see the same distance in feet (ft), metres (m), and kilometres (km), all derived from the same exact factors.
5. Use the ⇄ swap button to flip the orientation: the value in the yards field moves to the miles field and vice versa.
6. Click Copy miles or Copy yards to put the value on the clipboard.
7. The relationship rows at the bottom of the panel show the underlying equalities: 1 mile = 1 760 yd, 1 yard = 3 ft, 1 mile = 5 280 ft = 1 609.344 m = 1.609344 km. Every other value in the panel falls out of those equalities by integer multiplication or by the single exact 1 609.344 factor.

The Formulas

The single conversion factor that drives this tool is:

1 international statute mile = exactly 1 760 international yards

This is the value published in NIST Special Publication 811 (the SI Units Guide), the BIPM SI Brochure, and the legal metrology acts of the United States, United Kingdom, Canada, Australia, New Zealand, and South Africa. It is exact because the international yard was defined in 1959 as exactly 0.9144 metres. One mile is 1 760 yards, so 1 mi = 1 760 × 0.9144 m = 1 609.344 m exactly, which is 1.609344 km exactly. No rounding is involved at any step.

To convert miles to yards:

yards = miles × 1 760

The factor 1 760 is an integer, so the multiplication is exact at every scale: 0.5 mi = 880 yd exactly, 1 mi = 1 760 yd exactly, 10 mi = 17 600 yd exactly, 26.2 mi = 46 112 yd exactly, 100 mi = 176 000 yd exactly.

To convert yards to miles:

miles = yards / 1 760

The same integer in the denominator: 880 yd / 1 760 = 0.5 mi exactly, 1 760 yd / 1 760 = 1 mi exactly, 46 112 yd / 1 760 = 26.2 mi exactly.

The two formulas are exact inverses. If you convert a mile value to yards and then back to miles, you get the original value to machine precision (about 15 significant digits in JavaScript's IEEE 754 doubles). For the Miles To Yards, There is no drift and no accumulated error from repeated round-trips, because the factor is exact.

The bonus read-outs use three derived equalities, all of which follow from the same chain of definitions:

• 1 yard = exactly 3 feet, so feet = yards × 3 (exact integer) and feet = miles × 5 280 (exact integer, since 1 760 × 3 = 5 280).
• 1 yard = exactly 0.9144 metres, so metres = yards × 0.9144 (exact) and metres = miles × 1 609.344 (exact).
• 1 000 metres = exactly 1 kilometre, so kilometres = metres / 1 000 = miles × 1.609344 (exact).

The yard ⇄ metre factor 0.9144 and the mile ⇄ metre factor 1 609.344 are both exact by the 1959 agreement, so every bonus value inherits that exactness with no rounding ambiguity.

A rough mental shortcut: 1 mi ≈ 1 760 yd and 1 yd ≈ 0.91 m. For a tighter estimate, 1 mi ≈ 5 280 ft ≈ 1.6 km, and 100 yd ≈ 91 m ≈ 0.05 mi. These anchors are accurate to about half a percent, good enough for a casual guess but not for surveying, race timing, or engineering.

Worked Examples

Example 1, 1 mile. The single statute mile is exactly 1 × 1 760 = 1 760 international yards, exactly 5 280 feet, exactly 1 609.344 metres, exactly 1.609344 kilometres. This is the definition chain itself, every other example is just an integer multiple or sub-multiple of this one.

Example 2, 0.5 mile. Half a statute mile is exactly 0.5 × 1 760 = 880 yards, exactly 2 640 feet, exactly 804.672 metres. This is the length of a half-lap on a standard outdoor track, and the standard interval distance for interval training in imperial-unit systems.

Example 3, 2 miles. Two miles is exactly 2 × 1 760 = 3 520 yards, exactly 10 560 feet, exactly 3 218.688 metres. A 2-mile race is a standard US high-school distance on the cross-country circuit.

Example 4, 10 miles. Ten statute miles is exactly 10 × 1 760 = 17 600 yards, exactly 52 800 feet, exactly 16 093.44 metres, exactly 16.09344 kilometres. The 10-mile race is one of the standard US long-distance road-race distances alongside the 5K, 10K, half marathon, and marathon.

Example 5, marathon (26.2 mi). The rounded marathon is 26.2 statute miles = exactly 26.2 × 1 760 = 46 112 yards = exactly 138 336 feet = exactly 42 164.8128 metres. The international marathon distance is 42.195 km exactly by World Athletics rule 260.14b, which equals 26.2193827826009 mi exactly. The 26.2-mile convention survives because the 1908 Olympic marathon course was measured at 26 mi 385 yd, and that figure is still quoted in race programmes.

Example 6, 100 yards. One hundred international yards is exactly 100 × 3 = 300 feet, exactly 100 × 0.9144 = 91.44 metres, exactly 91.44 / 1 000 = 0.09144 kilometres, exactly 100 / 1 760 ≈ 0.056818181818... miles. This is the length of an American football field from the back of one end zone to the back of the other. The same 100 yd also equals 91.44 m, which is why American football fields and 100-metre sprint tracks look almost the same length even though they differ by 8.56 metres.

Example 7, round-trip check. Take 1 mi. Multiply by 1 760 to get 1 760 yd. Divide by 1 760 to get 1.000000000 mi. Multiply by 5 280 to get 5 280 ft. Multiply 5 280 ft by 0.3048 m/ft to get 1 609.344 m. Multiply by 1.609344 to get 1.609344 km. Every step is exact; round-trip drift is zero.

Where It Shows Up

Mile-to-yard conversions appear wherever a distance is reported in one imperial unit and the reader thinks in the other, almost always at the boundary between a US source and an international or metric consumer.

American football. A football field is 100 yd long between the back of the end zones (the playing field is 100 yd, plus two 10-yd end zones, for a total of 120 yd, or 360 ft, or 109.728 m, or 0.0625 mi exactly). Broadcast graphics, stadium signage, and the league's own rule book all quote yardages; international viewers and metric-system sports journalists have to translate every play into metres. A 10-yard gain is 9.144 m, a 50-yard field goal is 45.72 m, and a 99-yard touchdown run is 90.53 m.

Golf. A US golf course is measured in yards from the tee markers to the centre of the green, with typical total yardages of 5 500 to 7 500 yd. A 6 800-yd course is 6 800 / 1 760 ≈ 3.864 mi, or about 6.215 km. International broadcasts routinely convert course yardages to metres (6 800 yd × 0.9144 = 6 217.92 m) for non-US audiences.

Cricket. Test and first-class cricket grounds typically have a boundary between 65 yd (the ICC minimum for men's international cricket) and about 90 yd at the largest grounds. The MCG in Melbourne uses a 90-yd boundary in some matches and an 80-yd boundary in others; Lord's in London uses about 67 yd. Translating 65 yd into metres gives exactly 59.436 m, and 90 yd into miles gives exactly 0.051136363636... mi.

Running, athletics, and swimming. Mile-based track intervals, 5K (3.107 mi = 5 468 yd), 10K (6.214 mi = 10 936 yd), the marathon (26.219 mi = 46 112 yd exactly). Swimming pools in the United States are typically 25 yd (short course) or 50 yd; international and Olympic pools are 25 m or 50 m. A 25-yd pool is exactly 22.86 m, and a 50-yd pool is exactly 45.72 m, close to but distinct from the 25 m and 50 m metric pools.

Real estate and surveying. US deed descriptions still use yards and chains (1 chain = 22 yd exactly) for boundary measurements. A parcel described as 220 yd by 440 yd in the deed appears as 0.125 mi by 0.25 mi on a tax map, and as 201.168 m by 402.336 m on a metric survey.

Race timing and course certification. Mile-based road races are measured in miles in the entry form but in yards or metres on the official measurement certificate. Course certifiers use a Jones counter calibrated in metres and convert to miles and yards at every step.

Common Mistakes

Confusing yards with metres. A 100-yd football field is 91.44 m, not 100 m, and a 100 m sprint is 109.36 yd, not 100 yd. The two units are close enough to confuse at a glance, and the 8.56-yard (7.84 m) gap on a 100-unit measurement has caused international athletics disputes and course-certification failures. When the unit symbol is not present (a track marked "100" with no "m" or "yd"), the measurement is ambiguous.

Confusing statute miles with nautical miles. A statute mile is exactly 1 760 yd / 1 609.344 m, while a nautical mile is exactly 1 852 m (about 15 percent longer, or roughly 2 025.37 yd). Speeds called "knots" are nautical miles per hour, not statute miles per hour. Mixing them up in aviation, maritime, or meteorology is one of the most common sources of large distance errors.

Rounding the yard to 0.91 m or 0.914 m. The international yard is exactly 0.9144 m, fixed by the 1959 agreement. Rounding it to 0.91 m introduces an error of about 0.49 percent (about 0.49 yd on a 100-yd measurement, or about 11.6 yd on a mile). Rounding to 0.914 m introduces an error of about 0.04 percent, better but still not exact.

Rounding 1 760 to 1 800 or 1 750. Using 1 mi ≈ 1 800 yd introduces an error of about 2.3 percent (about 40 yd on a mile, or about 1.3 km on a 100-mile measurement). Using 1 mi ≈ 1 750 yd introduces an error of about 0.57 percent. The exact value is exactly 1 760 by the 1959 agreement.

Mixing US survey yards with international yards. The US survey yard was defined as 3600/3937 m until it was effectively retired on 1 January 2023 in favour of the international yard for most US federal surveying applications. The difference is about 2 parts per million, too small to matter outside legal-property descriptions, but for high-precision cadastral work the wrong yard can introduce a surveyor's offset of inches over miles.

Frequently Asked Questions

How many yards are in 1 mile? Exactly 1 760 international yards. The international yard has been exactly 0.9144 metres since 1 July 1959, when the English-speaking nations signed the international yard and pound agreement, and one international mile is exactly 1 760 of those yards. NIST SP 811, the BIPM SI Brochure, and the legal metrology acts of every country that uses the yard and mile all cite this exact value.

How many miles are in 1 yard? Exactly 1 / 1 760 = 0.00056818181818... statute miles. The decimal repeats forever (1/1 760 is a non-terminating decimal because 1 760 has factors other than 2 and 5), so for practical purposes the answer is rounded to 0.000568 mi at six decimal places.

Is 1 mile exactly 1 760 yards? Yes, since 1 July 1959. The international yard was defined as exactly 0.9144 metres on that date, and one international mile is 1 760 international yards, so 1 mi = 1 760 × 0.9144 m = 1 609.344 m exactly. The factor has not changed in the 67 years since, and there is no proposal to change it.

Is the UK yard the same as the US yard? Yes, in everyday use. Both the United Kingdom and the United States adopted the international yard of exactly 0.9144 m on 1 July 1959. Before that date the UK yard (the Imperial yard) was fractionally different from the US customary yard, about 2 parts per million, but those differences have been legally obsolete for more than six decades.

How long is an American football field in yards, feet, and metres? The playing field is exactly 100 yd long between the back of each end zone, plus two 10-yd end zones for a total marked field of 120 yd. In other units, the playing field is exactly 300 ft or exactly 91.44 m. The total marked field including both end zones is exactly 360 ft or exactly 109.728 m.

How many yards are in a 5K race? A 5K is exactly 5 kilometres = exactly 5 000 m. Since 1 yd = 0.9144 m exactly, the 5K is exactly 5 000 / 0.9144 = 5 468.06649... yd, or 5 468 yd rounded to whole yards. In miles, 5K is exactly 5 / 1.609344 = 3.10685596... mi, which equals 5 468.06649... yd when divided by 1 760.

How many yards are in a marathon? The international marathon is exactly 42.195 km by World Athletics rule 260.14b. Converting: 42 195 m / 0.9144 m/yd = 46 145.66929... yd, or 46 146 yd rounded to whole yards. In miles, the marathon is exactly 26.2193827826009... mi, which equals 26.2193827826009 × 1 760 = 46 145.66929... yd. The conventional "26.2 miles" figure (from the 1908 Olympic course) is exactly 46 112 yd.

What about the US survey yard? The US survey yard was 3600/3937 metres, slightly longer than the international yard (about 2 parts per million, or about 1.8 mm on a yard-stick). The US survey yard was effectively retired on 1 January 2023 in favour of the international yard for most US federal surveying applications. For everyday length conversions, the international yard of exactly 0.9144 m is the correct value to use.

Is a nautical mile the same as a statute mile? No. A nautical mile is exactly 1 852 metres (about 15 percent longer than a statute mile, or roughly 2 025.37 yd). A speed of "knots" is nautical miles per hour, not statute miles per hour. Mixing them up is one of the most common mistakes in aviation, maritime, and meteorology.

How do I convert miles to yards in my head? A useful trick: 1 mi is about 1 760 yd, so 10 mi is about 17 600 yd and 100 mi is about 176 000 yd. For a slightly tighter estimate, 0.5 mi = 880 yd, 2 mi = 3 520 yd, and 5 mi = 8 800 yd. For exact work, always use the 1 760 factor.

q: can the Miles To Yards be used for professional or commercial purposes? A: Yes. The conversion factor 1 mile = 1 760 yards is exact by international definition (1959 international yard and pound agreement), with no measurement uncertainty, so the calculator is suitable for surveying, race timing, sports officiating, real-estate transactions, engineering, and any other professional or commercial application that requires an exact imperial unit conversion.

For the Miles To Yards, How often are the Miles To Yards formulas updated? A: The conversion factor 1 international mile = 1 760 yards was fixed on 1 July 1959 and has not been revised since. There is no proposal to change it. The international yard itself was redefined in terms of the metre as exactly 0.9144 m on the same date, and the metre is itself defined by the SI (since the 2019 SI redefinition, the metre is defined by fixing the speed of light in vacuum c = 299 792 458 m/s exactly), so the relationship between the international yard, the international mile, and the metre is permanent and exact.
