mile per second to kilometer per hour
Convert mile per second (mi/s) to kilometer per hour (km/h). Use an editable speed converter, conversion formula, and reference table.
1 mi/s = 5,793.6384 km/h
Conversion formula
One mile per second equals 5,793.6384 kilometer per hour. Multiply your value in mile per second by this factor to get kilometer per hour. For the reverse conversion, divide by the same factor.

About these measurements
Speed is distance traveled per unit of time.
The base reference used here is the meter per second. One mile per second is 1,609.344 base units; one kilometer per hour is 0.2777777778 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.
