How to convert kilometers per hour to feet per second
ft/s = km/h × 0.9113444153Because one foot per second equals 1.09728 kilometers per hour, you can also divide: ft/s = km/h ÷ 1.09728.
A kilometer per hour is smaller than a foot per second: it takes 1.09728 kilometers per hour to make one foot per second.
