Info about "Kilometers per hour"

Kilometers per hour is used as a standard unit in transportation, therefore it is used in traffic or to measure the travel speed of vehicles. For example, a commercial aircraft flies at a speed of 1,000 km/h then it covers a distance of 1,000 kilometers per hour.

The unit is defined as follows: An object moving at 1 "km/h" per hour will cover one kilometer. "km/h" is approved to use in the international system of units (SI).

Info about "Miles per hour"

The unit of length known as a "mile" and it should not be confused with the nautical mile and very commonly used in the Anglo-American countries. Therefore, the metric system is defined in miles (instead of kilometers) per time unit. For example, if a vehicle travels at a speed of 100 miles per hour (100 mph), it will move around 160 km per hour in the metric system.

The units are defined as follows: An object moving at 1 "mph" per hour will cover a distance of one mile. Therefore, 1 mile is equivalent to 1.609344 kilometers.
