How to convert kilometers per hour to feet per second
Speed combines distance and elapsed time. Knots use the international nautical mile (1852 m), and mph uses the international statute mile (1609.344 m).
ft/s = km/h × 0.9113444153One kilometer per hour is 0.9113444153 feet per second, so a single multiplication converts any value.

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
