Frequently Asked Questions
-
What units does this converter convert between?
-
It converts power values from milliwatt (mW), used for low electrical power, to horsepower (550 ft*lbf/s), an imperial unit for mechanical power.
-
Why would I convert milliwatts to horsepower?
-
To compare or relate small electrical power levels common in electronics to larger mechanical power ratings found in engines and machinery.
-
Is this conversion accurate for detailed engineering use?
-
While useful for general comparisons, the results are approximate and may not suffice for high-accuracy engineering calculations without additional precision factors.
Key Terminology
-
Milliwatt (mW)
-
A unit equal to one thousandth of a watt, measuring low electrical power transfer rates.
-
Horsepower (550 ft*lbf/s)
-
An imperial unit of mechanical power equal to 550 foot‑pound‑force per second, commonly used to rate engines.
-
Power
-
The rate at which energy is transferred or converted, measured in various units depending on context.
