ft/s to km/h · speed conversion
What are feet per second and kilometers per hour?
Feet per second is an imperial speed unit used in ballistics and some engineering. Kilometers per hour is the standard metric unit for vehicle speed in most countries. For reference: a brisk walk is about 5 km/h (3 mph), and highway speed is around 100 km/h (62 mph).
How to convert feet per second to kilometers per hour
1 ft/s = 1.09728 km/h. To convert, multiply the number of feet per second by 1.09728. For example, 5 ft/s = 5.4864 km/h, and 20 ft/s = 21.9456 km/h. To go the other way, multiply kilometers per hour by 0.911345 (since 1 km/h = 0.911345 ft/s).
