5 mph = (5 × 1.609344) = 8.04672 km/h


Miles per hour and kilometers per hour are both units supplied to meacertain speed. Keep reading to learn more about each unit of measure.


Miles Per Hour

Miles per hour are a measurement of rate expressing the distance traveled in miles in one hour.<2>

The mile per hour is a US customary and also royal unit of rate. Miles per hour can be abbreviated as mph, and also are additionally sometimes abbreviated as mi/h or MPH. For example, 1 mile per hour can be composed as 1 mph, 1 mi/h, or 1 MPH.

Miles per hour deserve to be expressed using the formula: vmph = dmithr

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

Kilometers Per Hour

Kilometers per hour are a measurement of rate expressing the distance traveled in kilometers in one hour.

The kilometer per hour, or kilometre per hour, is an SI unit of rate in the metric mechanism. Kilometers per hour have the right to be abbreviated as km/h, and are also periodically abbreviated as kph. For instance, 1 kilometer per hour deserve to be created as 1 km/h or 1 kph.

In formal expressions, the slash, or solidus (/), is offered to separate units used to suggest department in an expression.
