How to Convert Horsepower to Btu Per Hour

To convert horsepower to a btu per hour measurement, use one of the formulas below.

Mechanical Horsepower to Btu Per Hour

Formula to convert mechanical horsepower to btu per hour:

btu per hour = hp(I) × 2,544.434187

Since one mechanical horsepower is equal to 2,544.434187 btu per hour, the formula to find btu per hour is to multiply mechanical horsepower by 2,544.434187.

For example, here's how to convert 5 mechanical horsepower to btu per hour using the formula.
5 hp(I) = (5 × 2,544.434187) = 12,722.170934 Btu/h

Electric Horsepower to Btu Per Hour

Formula to convert electric horsepower to btu per hour:

btu per hour = hp(E) × 2,545.458268

Since one electric horsepower is equal to 2,545.458268 btu per hour, the formula to find btu per hour is to multiply electric horsepower by 2,545.458268.

For example, here's how to convert 5 electric horsepower to btu per hour using the formula.
5 hp(E) = (5 × 2,545.458268) = 12,727.291339 Btu/h

Metric Horsepower to Btu Per Hour

Formula to convert metric horsepower to btu per hour:

btu per hour = hp(M) × 2,509.626507

Since one metric horsepower is equal to 2,509.626507 btu per hour, the formula to find btu per hour is to multiply metric horsepower by 2,509.626507.

For example, here's how to convert 5 metric horsepower to btu per hour using the formula.
5 hp(M) = (5 × 2,509.626507) = 12,548.132534 Btu/h

Boiler Horsepower to Btu Per Hour

Formula to convert boiler horsepower to btu per hour:

btu per hour = hp(S) × 33,471.411364

Since one boiler horsepower is equal to 33,471.411364 btu per hour, the formula to find btu per hour is to multiply boiler horsepower by 33,471.411364.

For example, here's how to convert 5 boiler horsepower to btu per hour using the formula.
5 hp(S) = (5 × 33,471.411364) = 167,357.056822 Btu/h

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

Horsepower

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

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

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.[2] 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.[3]

Boiler horsepower can be abbreviated as hp(S), for example 1 boiler horsepower can be written as 1 hp(S).

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.
