Yards to km converter, yards to kilometers.

To convert yards to km, multiply the yards by 0.0009144. So 1,000 yards is 0.9144 km and 10,000 yards is 9.144 km. The factor is exact: a yard is 0.9144 m and a kilometer is 1,000 m. The answer is a finite decimal, so nothing is rounded unless you choose fewer decimals. Going the other way, a kilometer is 1,093.6133 yards.

How to use the converter

1. Type the distance in the Yards (yd) box. The page opens on 1,000 yards.
2. Read the kilometers in the big result. The cards show miles, meters and feet.
3. Set Decimals and press Copy result or Copy link. Click a row of Common values to load it, or Print chart for a sheet.
4. The swap button (or S) turns kilometers into yards, which is handy when a course length is in km.

The mile is the check

There are 1,760 yards in a mile and a mile is exactly 1.609344 km, so 1,760 yards is exactly 1.609344 km. If your answer for 1,760 yards is not that, something is off. NIST Handbook 44 (2026), Appendix C (checked 26 Oct 2026) states 1 mile as 1,760 yards and 1,609.344 meters, and NIST Special Publication 811, Appendix B.8 marks the yard as exactly 0.9144 m.

Where yards turn into kilometers

• Golf. A course listed at 7,000 yards is 6.4008 km end to end. A 450 yard hole is 0.4115 km.
• Running tracks. A 440 yard lap, a quarter mile, is 0.40234 km. An 880 yard run is 0.80467 km.
• The marathon. 26 miles 385 yards is 46,145 yards, which is 42.194988 km. The race is set at 42.195 km, 12 millimeters longer.
• Swim and open water. A 1,000 yard swim is 0.9144 km, shorter than a 1 km swim by about 86 meters.

Worked examples

• 2,500 yards. 2,500 × 0.0009144 = 2.286 km.
• 12,000 yards. 10.9728 km.
• 100 yards. 0.09144 km, which is 91.44 m.
• 50,000 yards. 45.72 km.
• 1,093.6133 yards. About 1 km.

Adding several lengths

If you have several stretches in yards, add the yards first and convert the total once. Converting each and adding the rounded kilometers lets small rounding errors pile up, and for a few long distances the sum can drift in the last digit.

A quick estimate

Shift the decimal three places and take 9 percent off. 5,000 yards becomes 5, less 9 percent is 4.55, against the exact 4.572. That is 0.5 percent low. A kilometer is close to 1,100 yards: 1,094 to be exact.

Mistakes

Do not multiply by 0.9144 and stop: that gives meters. Move the decimal point three places to get kilometers. And check that a distance in yards is a distance and not an area. For a short distance in meters see yards to meters, and for miles miles to yards.
