## How to Convert Kilometers Per Second to Miles Per Hour

To convert a kilometer per second measurement to a mile per hour measurement, multiply the speed by the conversion ratio. One kilometer per second is equal to 2,236.936292 miles per hour, so use this simple formula to convert:

The speed in miles per hour is equal to the kilometers per second multiplied by 2,236.936292.

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

Kilometers per second and miles per hour 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 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.

## Miles Per Hour

Miles per hour are a measurement of speed expressing the distance travelled in miles in one hour.

The mile per hour is a US customary and imperial unit of speed. Miles per hour can be abbreviated as *mph*, and are also sometimes abbreviated as *mi/h* or *MPH*. For example, 1 mile per hour can be written as 1 mph, 1 mi/h, or 1 MPH.

Miles per hour can be expressed using the formula:

v_{mph} = d_{mi}t_{hr}

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