What does kilowatt (kW) measure?

Kilowatt (kW) is a unit of power representing 1,000 watts, measuring the rate of energy transfer or conversion, commonly used for electrical and mechanical power.

What applications use Btu (th)/second?

Btu (th)/second is used to quantify thermal energy flow in heating, cooling, and energy-conversion systems such as HVAC equipment and boilers.

Can I use this converter for mechanical power?

This conversion is specific to thermal power; mechanical power conversions require different contexts and units.

What Is This Tool?

This converter transforms power values from kilowatt (kW), a standard unit for electrical and mechanical power, to Btu (th)/second, which measures thermal energy transfer rate. It is useful in contexts involving heat flow and energy conversion.

How to Use This Tool?

Enter the power value in kilowatt (kW) into the input field.
Select kilowatt as your starting unit and Btu (th)/second as the target unit.
Click convert to view the equivalent power in Btu (th)/second.
Use the result to analyze or compare thermal power values in your system.

Key Features

Converts power values from kilowatt (kW) to Btu (th)/second (Btu (th)/s).
Browser-based and easy to use interface.
Applies to thermal power measurement relevant to HVAC and heating systems.
Provides accurate conversion using a defined conversion factor.

Examples

Convert 5 kW: 5 × 0.9484516527 = 4.7422582635 Btu (th)/s.
Convert 10 kW: 10 × 0.9484516527 = 9.484516527 Btu (th)/s.

Common Use Cases

Determining the thermal power capacity of HVAC units like furnaces and air conditioners.
Measuring boiler and heat exchanger output in industrial and building systems.
Performing heat transfer rate calculations in energy performance testing and simulation.

Tips & Best Practices

Confirm that power measurements are steady-state for accurate conversions.
Use this conversion mainly for thermal power contexts, not purely electrical or mechanical.
Double-check unit selections to avoid errors in results.

Limitations

Assumes steady-state power transfer, not capturing transient or variable efficiencies.
Btu (th)/second applies specifically to thermal power, not all power types.
Results may be affected by rounding due to decimal precision of the conversion factor.
