About This Tool
This Speed Converter is a tool for everyday use, transportation, and science. It converts units of speed (or velocity), which is the magnitude of the rate of change of an object's position. The base unit is the meter per second (m/s).
From vehicle speeds (km/h and mph) and aircraft or ship speeds (knots) to fundamental physical constants like the speed of sound and light, this tool covers the most important units for measuring motion.
Tips & Features
- m/s: The SI Standard: The meter per second (m/s) is the SI unit for speed. It is derived from the base units of length (meter) and time (second).
- MPH vs. km/h: Miles per hour (mph) is the standard in the United States and the UK, while kilometers per hour (km/h) is used in most other countries. 1 mph is approximately 1.609 km/h.
- Knots: A knot is a unit of speed equal to one nautical mile per hour. It is the primary unit used in maritime and aviation navigation because a nautical mile is related to the degrees of latitude on Earth's surface.
