What does electric horsepower represent?

Electric horsepower is a unit of power rating for electric motors, defined exactly as 746 watts, reflecting the mechanical work produced by an electric machine.

What is Btu (IT)/hour used for?

Btu (IT)/hour measures heat transfer rate and is commonly used to rate HVAC equipment capacity and heating system outputs.

Can this conversion be used for precise mechanical to thermal power calculations?

No, since horsepower (electric) and Btu (IT)/hour represent different phenomena, the conversion is mainly for comparative energy usage purposes.

Enter the value in electric horsepower you want to convert
Select horsepower (electric) as the input unit and Btu (IT)/hour as the output unit
Click convert to get the equivalent heat transfer rate in Btu (IT)/hour

Key Features

Converts electric horsepower (exactly 746 watts) to Btu (IT)/hour heat transfer rates
Browser-based and easy to use with quick input and output
Supports applications in HVAC, industrial heating systems, and energy analysis

Examples

2 horsepower (electric) equals 5090.915316627 Btu (IT)/hour
0.5 horsepower (electric) equals 1272.728829157 Btu (IT)/hour

Common Use Cases

Motor specification and performance rating for pumps, fans, and compressors
Sizing motor controllers and electrical supplies for industrial equipment
Translating electrical motor power into useful thermal energy units in HVAC and heating system design

Tips & Best Practices

Verify unit selections before converting to ensure correct input and output
Use this conversion for comparative energy or heat transfer evaluations, not for direct mechanical to thermal power equivalence
Consider system efficiency and instantaneous operating conditions for practical applications

Limitations

Horsepower (electric) and Btu (IT)/hour measure different physical quantities—mechanical power vs. heat transfer rate
Conversion is primarily useful for indirect comparative energy studies rather than exact power matching
System efficiencies, power factors, and operating conditions must be accounted for when applying results
