Convert Kilometers per hour to feet per second
1 kilometer per hour = 0.911344 feet per second · ft/s = km/h ÷ 1.09728
When you need this conversion
This conversion goes from kilometers per hour, the road speed unit in most countries, to feet per second, used in ballistics and US engineering. Both measure the same physical quantity, so the conversion is exact — the difference is which unit your source, tool, or region happens to use.
