Conversion Calculators
Speed Converter
Convert speed between meters per second, kilometers per hour, miles per hour, feet per second, and knots.
Quick guide
Enter a speed and choose the units to convert between meters per second, kilometers per hour, miles per hour, feet per second, and knots. Each conversion combines a distance factor with a time factor.
Read the full explanationHow It Works
Speed is distance over time, so conversion combines the length and time factors. One knot is one nautical mile per hour.
Formula Used
value × from-factor ÷ to-factor (base unit: m/s).
Example Calculation
100 km/h ≈ 62.14 mph ≈ 27.78 m/s.
Practical Use Cases
- Convert speed limits when driving abroad.
- Compare running and cycling paces.
- Work with aviation and marine speeds in knots.
