About these measurements

Speed is distance traveled per unit of time.

The base reference used here is the meter per second. One nautical mile per second is 1,852 base units; one kilometer per second is 1,000 base units.

Important distinctions

Mach is excluded because the speed of sound depends on medium and temperature.

Precision

The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
