Conversion formula

mph = mi/s × 3,600

One mile per second equals 3,600 mile per hour. Multiply your value in mile per second by this factor to get mile per hour. For the reverse conversion, divide by the same factor.

Worked example

To convert 5 mile per second:
5 × 3,600 = 18,000 mph

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 mile per hour is 0.44704 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.
