# Kilometers Per Second to Feet Per Second Conversion

Enter the speed in kilometers per second below to get the value converted to feet per second.

Results in Feet Per Second: 1 km/s = 3,280.839895 ft/s

## How to Convert Kilometers Per Second to Feet Per Second To convert a kilometer per second measurement to a foot per second measurement, multiply the speed by the conversion ratio.

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 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.
5 km/s = (5 × 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.

## 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 formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.

Kilometers per second can be expressed using the formula:
vkm/s = dkmtsec

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

## 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:
vft/s = dfttsec

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