Electric horsepower is equal to the power in btu per hour multiplied by 0.000392856568.

**For example,**here's how to convert 5,000 btu per hour to electric horsepower.

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

## Btu Per Hour

One BTU per hour is equal to one british thermal unit, or the energy needed to heat one pound of water 1 °F, for one hour.

The btu per hour is a US customary unit of power. Btu per hour can be abbreviated as *Btu/h*; for example, 1 btu per hour can be written as 1 Btu/h.

## 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.
