To convert a measurement in feet per second to a measurement in kilometers per hour, multiply the speed by the following conversion ratio: 1.09728 kilometers per hour/foot per second.

Since one foot per second is equal to 1.09728 kilometers per hour, you can use this simple formula to convert:

kilometers per hour = feet per second × 1.09728

The speed in kilometers per hour is equal to the speed in feet per second multiplied by 1.09728.

For example, here's how to convert 5 feet per second to kilometers per hour using the formula above.
kilometers per hour = (5 ft/s × 1.09728) = 5.4864 km/h

Feet per second and kilometers per hour are both units used to measure speed. Calculate speed in feet per second or kilometers per hour using our speed calculator or keep reading to learn more about each unit of measure.

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.

In the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units.[1] For example, ft/s is expressing a change in length or distance relative to a change in time.

Feet per second can be expressed using the formula:
vft/s = dfttsec

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

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.

Kilometers per hour can be expressed using the formula:
vkm/h = dkmthr

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