Understanding Speed Units
Speed measures how fast an object moves over a distance. Common units include:
- mph (miles per hour) - Imperial unit commonly used in the US
- kph (kilometers per hour) - Metric unit used worldwide
- m/s (meters per second) - SI base unit for velocity
- knots - Nautical speed unit (1 knot = 1 nautical mile per hour)
- ft/s (feet per second) - Imperial unit for shorter distances
Common Conversion Formulas
- mph to kph: multiply by 1.609344
- kph to mph: multiply by 0.621371
- m/s to mph: multiply by 2.236936
