How to Convert Kilometers per Hour to Feet per Second

To convert a kilometer per hour measurement to a foot per second measurement, multiply the speed by the conversion ratio.

Since one kilometer per hour is equal to 0.911344 feet per second, you can use this simple formula to convert:

feet per second = kilometers per hour × 0.911344

The speed in feet per second is equal to the kilometers per hour multiplied by 0.911344.

For example, here's how to convert 5 kilometers per hour to feet per second using the formula above.

5 km/h = (5 × 0.911344) = 4.556722 ft/s

Kilometers per hour and feet per second are both units used to measure speed. Keep reading to learn more about each unit of measure.

What Are Kilometers per Hour?

Kilometers per hour are a measurement of speed expressing the distance traveled in kilometers in one hour.

The kilometer per hour, or kilometre per hour, is an SI unit of speed in the metric system. Kilometers per hour can be abbreviated as km/h, and are also sometimes abbreviated as kph. For example, 1 kilometer per hour can be written as 1 km/h or 1 kph.

In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.^[1]

Kilometers per hour can be expressed using the formula:
v_km/h = d_km / t_hr

The velocity in kilometers per hour is equal to the distance in kilometers divided by time in hours.

What Are Feet per Second?

Feet per second are a measurement of speed expressing the distance traveled in feet in one second.

The foot per second is a US customary and imperial unit of speed. Feet per second can be abbreviated as ft/s, and are also sometimes abbreviated as ft/sec or fps. For example, 1 foot per second can be written as 1 ft/s, 1 ft/sec, or 1 fps.

Feet per second can be expressed using the formula:
v_ft/s = d_ft / t_sec

The velocity in feet per second is equal to the distance in feet divided by time in seconds.
