## How to Convert Feet Per Second to Kilometers Per Second

To convert a foot per second measurement to a kilometer per second measurement, multiply the speed by the conversion ratio. One foot per second is equal to 0.000305 kilometers per second, so use this simple formula to convert:

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

**For example,**here's how to convert 5 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.

## Feet Per Second

Feet per second are a measurement of speed expressing the distance travelled 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.

## Kilometers Per Second

Kilometers per second are a measurement of speed expressing the distance travelled 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.
