How to convert yards to kilometers
Length conversion changes the unit of a distance. Area and volume need squared and cubed factors; this calculator does not convert square feet or cubic feet.
Use x for the value in yd, b for the intermediate value in m, and y for the result in km.
km = yd × 0.9144 ÷ 1000
Worked examples
10 yd ≈ 0.009144 km
Step 1: (10 × 0.9144) ≈ 9.144 m.
Step 2: 9.144 ÷ 1000 ≈ 0.009144 km.20 yd ≈ 0.018288 km
Step 1: (20 × 0.9144) ≈ 18.288 m.
Step 2: 18.288 ÷ 1000 ≈ 0.018288 km.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Yards
The international yard is exactly 0.9144 meters, or three feet. It is used for fabric lengths and field dimensions.
About Kilometers
A kilometer is 1,000 meters. It is useful for road distances and routes; it measures distance rather than speed.
Definitions and sources
Use consistent length units when carrying dimensions into construction calculations.
