mile per hour to centimeter per second
Convert mile per hour (mph) to centimeter per second (cm/s). Use an editable speed converter, conversion formula, and reference table.
1 mph = 44.704 cm/s
Conversion formula
One mile per hour equals 44.704 centimeter per second. Multiply your value in mile per hour by this factor to get centimeter per second. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 mile per hour:5 × 44.704 = 223.52 cm/s

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 centimeter per second is 0.01 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.
