Speed Conversion

Speed conversions are essential for various applications, from transportation and sports to everyday measurements and environmental science. Understanding speed conversions ensures accurate and consistent results across different measurement systems.

Common Speed Units

Metric Units

Meters per Second (m/s)
Kilometers per Hour (km/h)
Centimeters per Second (cm/s)
Millimeters per Second (mm/s)

Other Units

Miles per Hour (mph)
Feet per Second (ft/s)
Knots (kn)
Mach (M)

Common Applications

Field	Measurement Types	Typical Uses
Transportation	Kilometers per Hour, Miles per Hour	Vehicle speed, traffic management
Sports	Meters per Second, Kilometers per Hour	Athletic performance, race timing
Aviation	Knots, Mach	Aircraft speed, flight planning
Everyday Use	Kilometers per Hour, Miles per Hour	Walking speed, cycling

Conversion Tips

1 km/h equals approximately 0.621371 mph
1 mph equals approximately 1.60934 km/h
Remember that 1 knot = 1.15078 miles per hour
Speed is always a ratio of distance to time

Speed Conversions

Conversion	Formula/Rule	Quick Answer
Kilometers per Hour to Miles per Hour	1 mph = 1.60934 km/h	Divide km/h by 1.60934
Miles per Hour to Kilometers per Hour	1 km/h = 0.621371 mph	Multiply mph by 1.60934
Meters per Second to Kilometers per Hour	1 km/h = 0.277778 m/s	Multiply m/s by 3.6
Kilometers per Hour to Meters per Second	1 m/s = 3.6 km/h	Divide km/h by 3.6
Knots to Miles per Hour	1 mph = 0.868976 kn	Multiply kn by 1.15078
Miles per Hour to Knots	1 kn = 1.15078 mph	Divide mph by 1.15078
Mach to Miles per Hour	1 mph = 0.00130332 M	Multiply M by 767.269
Miles per Hour to Mach	1 M = 767.269 mph	Divide mph by 767.269
