Why convert electric horsepower to Btu (th)/hour?

Converting allows electrical motor power ratings to be understood in terms of thermal power, useful for HVAC and heating/cooling system designs.

Is electric horsepower the same as mechanical horsepower?

Electric horsepower specifically rates electric motors and is defined as exactly 746 watts, which may differ slightly from other horsepower types.

Does this conversion account for system efficiency?

No, the conversion presents a steady-state power equivalence and does not consider efficiency or energy losses.

What Is This Tool?

This converter transforms power values from electric horsepower, a unit for rating electric motors, into Btu (th)/hour, used to measure heat transfer rates. It aids in linking mechanical motor performance with thermal power metrics.

How to Use This Tool?

Enter the horsepower (electric) value you want to convert
Select horsepower (electric) as the input unit and Btu (th)/hour as the output unit
Click the convert button to get the equivalent thermal power value

Key Features

Converts electric horsepower to thermochemical British thermal units per hour
Helps integrate motor power ratings with HVAC and heating/cooling system specs
User-friendly interface requiring simple value input and unit selection

Examples

2 horsepower (electric) equals approximately 5094.32 Btu (th)/hour
0.5 horsepower (electric) converts to about 1273.58 Btu (th)/hour

Common Use Cases

Interpreting motor output power on nameplates for pumps and compressors
Designing and sizing HVAC systems to match electric motor power ratings
Specifying heat output in boilers, water heaters, and heat exchangers

Tips & Best Practices

Ensure the conversion context matches mechanical to thermal power application
Double-check unit selections before conversion to avoid misinterpretation
Use the tool for steady-state power comparisons, considering system efficiency separately

Limitations

Horsepower (electric) and Btu (th)/hour represent different types of power (mechanical vs thermal)
Conversion assumes steady-state equivalence without accounting for efficiency or losses
Not suitable for transient or dynamic power condition assessments
