How to Convert Kilometers per Second to Feet per Second

To convert a measurement in kilometers per second to a measurement in feet per second, multiply the speed by the following conversion ratio: 3,280.839895 feet per second/kilometer per second.

Since one kilometer per second is equal to 3,280.839895 feet per second, you can use this simple formula to convert:

feet per second = kilometers per second × 3,280.839895

The speed in feet per second is equal to the speed in kilometers per second multiplied by 3,280.839895.

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

feet per second = (5 km/s × 3,280.839895) = 16,404.199475 ft/s

Kilometers per second 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 Second?

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

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

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, km/s is expressing a change in length or distance relative to a change in time.

Kilometers per second can be expressed using the formula:
v_km/s = d_km / t_sec

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

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.
