Different units of speed are used based on regional and contextual preferences. For example, kilometers per hour is commonly used in most countries for road travel, while miles per hour is used in the USA and the UK. Knots are specifically used in aviation and maritime navigation.
To convert between different speed units, enter the speed value into our conversion tool in the unit you know, and it will automatically display the equivalent speed in other units.
Our speed calculator is able to be used for free on any device of any size, at any time of the day.
Mach number is a dimensionless quantity in fluid dynamics and aerodynamics describing the ratio of the speed of an object moving through a fluid to the local speed of sound. For example, Mach 1 is the speed of sound, Mach 2 is twice the speed of sound, etc.
The conversions in our tool are based on standard conversion factors recognized internationally. They are highly accurate and suitable for educational, professional, and personal uses.
A knot is a unit of speed equal to one nautical mile per hour, used in maritime (boats and ships) and aerial (aircraft) navigation to gauge the speed relative to the fluid (water or air).
A common misconception is confusing speed with velocity. Speed is a scalar quantity that refers only to the rate an object is moving, while velocity is a vector, describing both speed and the direction of motion.
