About Speed Conversion
Speed is the rate at which an object moves. The most common units of speed are:
Kilometers per hour (kph): Used in most countries around the world that follow the metric system.
Miles per hour (mph): Used primarily in the United States and the United Kingdom.
Meters per second (m/s): The SI unit of speed, commonly used in scientific contexts.
Feet per second (ft/s): Used in some engineering applications in the US.
Knots: Used in maritime and aviation contexts, equal to one nautical mile per hour.
Conversion Formulas
KPH to MPH: mph = kph × 0.621371
MPH to KPH: kph = mph × 1.60934
KPH to m/s: m/s = kph × 0.277778
MPH to ft/s: ft/s = mph × 1.46667
KPH to Knots: knots = kph × 0.539957
