Kilometers per Hour to Knots Converter

What Are Kilometers per Hour?

Kilometers per hour are a measurement of speed expressing the distance traveled 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.

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, km/h is expressing a change in length or distance relative to a change in time.

Kilometers per hour can be expressed using the formula:
v_km/h = d_km / t_hr

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