What Is This Tool?
This converter transforms power values from electric horsepower to Btu (IT)/second, a unit representing heat transfer or thermal power. It is designed for engineers and technicians working with electric motors and thermal energy systems.
How to Use This Tool?
-
Enter the power value expressed in electric horsepower.
-
Select 'horsepower (electric)' as the input unit and 'Btu (IT)/second [Btu/s]' as the output unit.
-
Click the convert button to obtain the equivalent power in Btu (IT)/second.
Key Features
-
Converts electric horsepower, a common motor power rating defined as exactly 746 watts, to heat power in Btu (IT)/second.
-
Enables comparison of electrical and thermal power units in engineering and HVAC applications.
-
Simple input and output interface with clear unit definitions and example conversions.
Examples
-
5 horsepower (electric) equals approximately 3.535357859 Btu (IT)/second.
-
0.1 horsepower (electric) converts to about 0.07070715718 Btu (IT)/second.
Common Use Cases
-
Checking motor output power on pumps, fans, and compressors by converting to thermal power units.
-
Sizing motor controllers and electrical supply for industrial equipment where heat transfer rates are relevant.
-
Performing heat-transfer or energy balance calculations using British thermal units in HVAC and thermal engineering.
Tips & Best Practices
-
Ensure you are converting electric horsepower, as values differ for other horsepower types.
-
Use this conversion for comparing mechanical power with heat generation or thermal energy output.
-
Refer to exact unit definitions to maintain consistency in engineering documentation.
Limitations
-
Conversion assumes exact unit definitions without accounting for real-world inefficiencies or losses.
-
Rounding and defined constants limit precision; use direct measurements for critical thermal calculations.
-
Applicable only to electric horsepower; other horsepower definitions require different conversion factors.
