Megawatts to Horsepower Conversion (MW to hp)

How to Convert Megawatts to Horsepower

To convert a megawatt measurement to horsepower, use one of the formulas below.

Megawatts to Mechanical Horsepower

Formula to convert megawatts to mechanical horsepower:

hp(I) = megawatts ÷ 0.000746

Since mechanical horsepower is equal to 0.000746 megawatts, the formula to find mechanical horsepower is the power in megawatts divided by 0.000746.

For example, here's how to convert 0.005 megawatts to mechanical horsepower.

0.005 MW = (0.005 ÷ 0.000746) = 6.70511 hp(I)

Megawatts to Electric Horsepower

Formula to convert megawatts to electric horsepower:

hp(E) = megawatts ÷ 0.000746

Since electric horsepower is equal to 0.000746 megawatts, the formula to find electric horsepower is the power in megawatts divided by 0.000746.

For example, here's how to convert 0.005 megawatts to electric horsepower.

0.005 MW = (0.005 ÷ 0.000746) = 6.702413 hp(E)

Megawatts to Metric Horsepower

Formula to convert megawatts to metric horsepower:

hp(M) = megawatts ÷ 0.000735

Since metric horsepower is equal to 0.000735 megawatts, the formula to find metric horsepower is the power in megawatts divided by 0.000735.

For example, here's how to convert 0.005 megawatts to metric horsepower.

0.005 MW = (0.005 ÷ 0.000735) = 6.798108 hp(M)

Megawatts to Boiler Horsepower

Formula to convert megawatts to boiler horsepower:

hp(S) = megawatts ÷ 0.00981

Since boiler horsepower is equal to 0.00981 megawatts, the formula to find boiler horsepower is the power in megawatts divided by 0.00981.

For example, here's how to convert 0.005 megawatts to boiler horsepower.

0.005 MW = (0.005 ÷ 0.00981) = 0.50971 hp(S)

How Many Horsepower Are in a Megawatt?

There are 1,341.02209 horsepower in a megawatt, which is why we use this value in the formula above.

1 MW = 1,341.02209 hp

Megawatts and horsepower are both units used to measure power. Keep reading to learn more about each unit of measure.

Megawatts

One megawatt is the power equal to 1,000,000 watts, or the energy consumption at a rate of 1,000,000 joules per second.

The megawatt is a multiple of the watt, which is the SI derived unit for power. In the metric system, "mega" is the prefix for millions, or 10⁶. Megawatts can be abbreviated as MW; for example, 1 megawatt can be written as 1 MW.

Horsepower

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

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

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).

Metric Horsepower

One metric horsepower is the power needed to one metric horsepower as the lift a 75 kilogram mass at at one meter per second.^[1] One metric horsepower is equal to 735.49875 watts.

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

Boiler horsepower is used to measure the power of a boiler to generate steam. One boiler horsepower is equal to the power needed to evaporate 34.5 pounds in one hour.^[2]

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.^[3] Horsepower were later used to measure the power output of piston and turbine engines and electrical motors.
