1 yd = 0.0009144 km (yard → kilometer)
1 yd = 0.0009144 km
1 yard equals 0.0009144 kilometers. To convert yards to kilometers, multiply the yard value by 0.0009144. For quick reference: 1 yd = 0.0009144 km, 5 yd = 0.004572 km, 10 yd = 0.009144 km, 100 yd = 0.09144 km.
Kilometers = Yards × 0.0009144Yards to kilometres multiplies by 0.0009144 exactly. A 1760 yd mile is 1.609344 km; a 1000 yd rifle range is 0.9144 km. The conversion serves long-range sport shooting and golf-course totals, where yard-denominated American figures need translating for metric audiences. Since 1000 yd falls just short of a kilometre, the rounded mental model "a thousand yards is about a klick" runs 8.6 % long — acceptable in conversation, wrong in a range table where the difference is several minutes of angle.
Cross-country running courses measured historically in yards in older UK results archives need converting to kilometres to compare against modern race distances, which are almost universally metric now. A course once measured at 4,400 yd converts to 4.02 km, close to but not exactly the modern 4 km standard distance — comparing archived times to current results without this conversion overstates how the sport's pacing has changed. Treat yard-based historical distances as approximate; old course measurements were rarely as precise as modern certified courses.
Start with your value in yards.
Multiply the yard value by 0.0009144. This is the exact conversion factor from yards to kilometers.
The product is your value in kilometers. For example, 5 yd × 0.0009144 = 0.004572 km.
The exact factor from yards to kilometers is 0.0009144.

An American football field is 100 yards from goal line to goal line. An adult walking stride is roughly 1 yard.
The yard (yd) is a unit of length in the imperial and US customary systems, defined as exactly 0.9144 meters (3 feet). It is used in American football field measurements, fabric and textile retail, and many landscaping contexts. The international yard was harmonized with the imperial yard in 1959.
The kilometer (km) equals exactly 1,000 meters. It is the standard unit for road distances in almost every country except the United States and the United Kingdom. A 5K running race is 5 kilometers; a marathon is 42.195 km.
