## How to Convert Feet per Second to Kilometers per Second

To convert a measurement in feet per second to a measurement in kilometers per second, multiply the speed by the following conversion ratio: 0.000305 kilometers per second/foot per second.

Since one foot per second is equal to 0.000305 kilometers per second, you can use this simple formula to convert:

kilometers per second = feet per second × 0.000305

The speed in kilometers per second is equal to the speed in feet per second multiplied by 0.000305.

**For example,**here's how to convert 5,000 feet per second to kilometers per second using the formula above.

Feet per second and kilometers per second are both units used to measure speed. 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:

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.

## 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.

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.
