About these measurements

Speed is distance traveled per unit of time.

The base reference used here is the meter per second. One millimeter per second is 0.001 base units; one foot per second is 0.3048 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.

Common questions

How do I convert mm/s to ft/s?

Multiply the quantity in mm/s by 0.003280839895. You can also type the value into the converter above.

Can I reverse the conversion?

Yes. Use the swap button or open the foot per second to millimeter per second converter.
