How to Convert Milliwatts to Horsepower
To convert a milliwatt measurement to horsepower, use one of the formulas below.
Milliwatts to Mechanical Horsepower
Formula to convert milliwatts to mechanical horsepower:
hp(I) = milliwatts ÷ 745,699.871582
Since mechanical horsepower is equal to 745,699.871582 milliwatts, the formula to find mechanical horsepower is the power in milliwatts divided by 745,699.871582.
Milliwatts to Electric Horsepower
Formula to convert milliwatts to electric horsepower:
hp(E) = milliwatts ÷ 746,000
Since electric horsepower is equal to 746,000 milliwatts, the formula to find electric horsepower is the power in milliwatts divided by 746,000.
Milliwatts to Metric Horsepower
Formula to convert milliwatts to metric horsepower:
hp(M) = milliwatts ÷ 735,498.75
Since metric horsepower is equal to 735,498.75 milliwatts, the formula to find metric horsepower is the power in milliwatts divided by 735,498.75.
Milliwatts to Boiler Horsepower
Formula to convert milliwatts to boiler horsepower:
hp(S) = milliwatts ÷ 9,809,500
Since boiler horsepower is equal to 9,809,500 milliwatts, the formula to find boiler horsepower is the power in milliwatts divided by 9,809,500.
Milliwatts and horsepower are both units used to measure power. Keep reading to learn more about each unit of measure.
The milliwatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "milli" is the prefix for thousandths, or 10-3. Milliwatts can be abbreviated as mW; for example, 1 milliwatt can be written as 1 mW.
Electric and mechanical are the most commonly used types. One electric horsepower is equivalent to 746 watts and one mechanical horsepower is equivalent to 745.699872 watts.
Mechanical horsepower is often used to measure the output of engines and motors in North America. One mechanical horsepower is equal to 745.69987158227022 watts.
The mechanical horsepower is a US customary and imperial unit of power. Mechanical horsepower can be abbreviated as hp(I); for example, 1 mechanical horsepower can be written as 1 hp(I).
Electric horsepower is used to measure the output of electric motors and other electrical machines in the US. One electric horsepower is equal to exactly 746 watts.
The electric horsepower is a US customary and imperial unit of power. Electric horsepower can be abbreviated as hp(E); for example, 1 electric horsepower can be written as 1 hp(E).
The metric horsepower is a non-SI metric unit for power. Metric horsepower can be abbreviated as hp(M), and are also sometimes abbreviated as PS, cv, hk, pk, ks, or ch. For example, 1 metric horsepower can be written as 1 hp(M), 1 PS, 1 cv, 1 hk, 1 pk, 1 ks, or 1 ch.
Boiler horsepower can be abbreviated as hp(S); for example, 1 boiler horsepower can be written as 1 hp(S).
The term horsepower was adopted by Scottish inventor James Watt to measure the power output of his steam engine and to compare that power with that of horses horses. Horsepower were later used to measure the power output of piston and turbine engines and electrical motors.
