How do I convert milliwatts to mechanical horsepower?
Enter the value in milliwatts to find the same power quantity in mechanical horsepower. The number changes to match the unit; the underlying quantity stays the same. Check the definitions below when a unit has more than one convention.
Common uses
- Compare power ratings in different units.
- Translate power measurements on equipment specifications.
How it works
For the displayed direction, 1 mW equals 0.0000013410220896 hp mech. The engine converts through the shared power base quantity. Horsepower is mechanical unless marked metric. PS equals metric horsepower. Refrigeration tons use the US 12,000 BTU IT/h convention. The multiplier is derived from the two centralized unit factors. Keep full precision until the final result; displayed answers use up to 12 significant digits. SI prefixes specify powers of ten: femto 10^-15, pico 10^-12, nano 10^-9, micro 10^-6, milli 10^-3, kilo 10^3, mega 10^6, giga 10^9 and tera 10^12. Unit symbols are case-sensitive. The numerical conversion uses the ratio of the source and target scale factors.
Worked example
10 mW converts to 0.000013410220896 hp mech. For the reverse direction, swap the units and enter 0.000013410220896 hp mech; the result is approximately 10 mW.
