About these measurements
Speed is distance traveled per unit of time.
The base reference used here is the meter per second. One mile per hour is 0.44704 base units; one inch per second is 0.0254 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.
