Kilometers per hour and miles per hour are both units used to measure speed. Keep reading to learn more about each unit of measure.

## Kilometers Per Hour

Kilometers per hour are a measurement of speed expressing the distance travelled in kilometers in one hour.

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

Kilometers per hour can be expressed using the formula:

v_{km/s} = d_{km}t_{hr}

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

## 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.
