Speed is the rate at which an object moves in a specific direction. The two most common units for measuring speed are:
- Kilometers per hour (kph): Used in most countries worldwide that follow the metric system.
- Miles per hour (mph): Primarily used in the United States and the United Kingdom.
The conversion between these units is based on the relationship between kilometers and miles:
1 mile = 1.60934 kilometers
Therefore:
- To convert kph to mph: mph = kph × 0.6214
- To convert mph to kph: kph = mph × 1.6093
21 kph is a relatively moderate speed, typically achieved during a brisk jogging pace or a slow cycle ride.
