Speed is the rate at which an object moves in a specific direction. The two most common units for measuring speed are:
- Miles per hour (mph): Primarily used in the United States and the United Kingdom.
- Kilometers per hour (kmh): Used in most countries worldwide that follow the metric system.
The conversion between these units is based on the relationship between kilometers and miles:
1 mile = 1.60934 kilometers
Therefore:
- To convert mph to kmh: kmh = mph × 1.60934
- To convert kmh to mph: mph = kmh × 0.621371
1 mph is a relatively slow speed, typically associated with:
- Walking or casual cycling
- Nature walks or gentle hiking
