About converting Kilometers per Hour to Feet per Second
Kilometers per Hour (km/h) and Feet per Second (ft/s) are both units of speed, so converting between them is a single multiplication: multiply your Kilometers per Hour figure by 0.9113. Ten Kilometers per Hour comes to 9.1134 Feet per Second, and a hundred works out at 91.1344 Feet per Second.
Rule of thumb: going from Kilometers per Hour to Feet per Second divides, so the figure always shrinks — it takes about 1.0973 Kilometers per Hour to make a single Foot per Second. If your answer came out bigger, you have the conversion the wrong way round.
What is a Kilometer per Hour?
The kilometer per hour is the road-speed unit of nearly every country on Earth: the number on the speedometer, the number on the sign, the number in the ticket. It is a compound unit rather than a fundamental one — a distance divided by a time — and that is precisely why it took hold, because people already thought in kilometers and in hours and so needed no new idea to think in km/h. Its only real rivals are mph, which clings on in the United States and the United Kingdom, and the knot, which owns the sea and the sky.
What is a Foot per Second?
Feet per second is a working unit rather than a public one. It appears wherever American engineering needs a speed that pairs with dimensions already given in feet — conveyor and belt speeds, water flowing in a channel, air velocity in a duct — and above all in ballistics, where muzzle velocity has always been quoted in ft/s. It is also the unit US physics problems fall back on when they are posed in imperial, so it feels oddly familiar to anyone who learned mechanics from an American textbook. On a road sign it appears essentially never.
To put both in perspective: a typical motorway limit is around 120 kilometers per hour, while a rifle bullet leaves the muzzle at roughly 3,000 feet per second.

What is 100 Kilometers per Hour in Feet per Second?
100 Kilometers per Hour is equal to 91.1344 Feet per Second.
How do I convert Feet per Second to Kilometers per Hour?
Multiply the Feet per Second value by 1.0973 (or divide by 0.9113).
Is this Kilometers per Hour to Feet per Second conversion exact?
The definition is exact — Kilometers per Hour and Feet per Second are both fixed against the same base by international agreement — but the decimal shown here is rounded for readability, because the true ratio does not terminate. For engineering or scientific work, carry more decimal places than this page displays.
