Horsepower to Megawatts Conversion (hp to MW)

How to Convert Horsepower to Megawatts

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

Mechanical Horsepower to Megawatts

Formula to convert mechanical horsepower to megawatts:

megawatts = hp(I) × 0.000746

Since one mechanical horsepower is equal to 0.000746 megawatts, the formula to find megawatts is to multiply mechanical horsepower by 0.000746.

For example, here's how to convert 5 mechanical horsepower to megawatts using the formula.

5 hp(I) = (5 × 0.000746) = 0.003728 MW

Electric Horsepower to Megawatts

Formula to convert electric horsepower to megawatts:

megawatts = hp(E) × 0.000746

Since one electric horsepower is equal to 0.000746 megawatts, the formula to find megawatts is to multiply electric horsepower by 0.000746.

For example, here's how to convert 5 electric horsepower to megawatts using the formula.

5 hp(E) = (5 × 0.000746) = 0.00373 MW

Metric Horsepower to Megawatts

Formula to convert metric horsepower to megawatts:

megawatts = hp(M) × 0.000735

Since one metric horsepower is equal to 0.000735 megawatts, the formula to find megawatts is to multiply metric horsepower by 0.000735.

For example, here's how to convert 5 metric horsepower to megawatts using the formula.

5 hp(M) = (5 × 0.000735) = 0.003677 MW

Boiler Horsepower to Megawatts

Formula to convert boiler horsepower to megawatts:

megawatts = hp(S) × 0.00981

Since one boiler horsepower is equal to 0.00981 megawatts, the formula to find megawatts is to multiply boiler horsepower by 0.00981.

For example, here's how to convert 5 boiler horsepower to megawatts using the formula.

5 hp(S) = (5 × 0.00981) = 0.049048 MW

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

Horsepower

There are several types of horsepower, including mechanical, electrical, metric, boiler, brake, and indicated, and they all have different applications in industry. Mechanical and electrical are the most commonly used.

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.

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.
