Speed Converter
km/h, mph, knots and m/s.
1 meter per second = 2.236936292 mph. Enter any value to convert meters per second (m/s) to miles per hour (mph), or use the table below for common values.
mph = m/s × 2.236936292
Example: 10 m/s = 22.36936292 mph. To convert the other way, use m/s = mph × 0.44704.
Quick mental estimate: multiply by about 2.2.

The meter per second is the SI unit of speed, used in physics, engineering and for wind speed in weather science.
Miles per hour is the road speed unit in the United States and the United Kingdom.
Use the formula mph = m/s × 2.236936292. For example, 10 m/s = 22.36936292 mph.
1 m/s = 2.236936292 mph.
Use m/s = mph × 0.44704. 1 mph = 0.44704 m/s.
