How speed converter works
This converter handles common speed units used in everyday life, aviation, and physics. It works by first converting the input to meters per second (the base unit), then dividing by the target unit factor. For example, 1 mph equals 0.44704 m/s, and 1 km/h equals 0.277778 m/s.
The supported units are meters per second (m/s), kilometers per hour (km/h), miles per hour (mph), knots (nautical miles per hour), feet per second (ft/s), and Mach (the speed of sound, approximately 343 m/s at sea level).
This is useful for driving, aviation, sailing, cycling, and physics. The most common conversion is mph to km/h for international travel. Results are rounded to six decimal places.
