Kilowatt to BTU per Hour Conversion Table

Table showing various kilowatt measurements converted to btu/hr. Click any preset value or arrow to load it into the converter.

How to Convert Kilowatts to BTU/hr

To convert kilowatts to btu/hr, multiply the power by the following conversion ratio: 3,412.1416351 btu/hr/kilowatt.

Since one kilowatt is equal to 3,412.1416351 btu/hr, you can use this simple formula to convert:

btu/hr = kilowatts × 3,412.1416351

The power in btu/hr is equal to the power in kilowatts multiplied by 3,412.1416351.

For example, here's how to convert 5 kilowatts to btu/hr using the formula above.

btu/hr = (5 kW × 3,412.1416351) = 17,060.7081757 BTU/hr

How Many BTU/hr Are in a Kilowatt?

There are 3,412.1416351 btu/hr in a kilowatt, which is why we use this value in the formula above.

1 kW = 3,412.1416351 BTU/hr|1 BTU/hr = 0.000293071 kW

Our kilowatt to btu per hour calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Kilowatts and btu/hr are both units used to measure power. Keep reading to learn more about each unit.

What Is a Kilowatt?

A kilowatt is a unit of power equal to 1,000 watts (W), the base unit for power. Equal to 1,000 Watts (1 kJ/s). [1]

The kilowatt is classified as a metric and SI-compatible unit of power. Kilowatts can be abbreviated as kW; for example, 1 kilowatt can be written as 1 kW.

In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilowatt (kW) a convenient decimal multiple of the watt (W).

In practice, kilowatts (kW) are widely used across large-scale industrial, bulk, and macro-level power specifications within SI metric workflows, engineering documentation, and technical data sheets.

What Is a BTU per Hour?

A btu per hour is a unit of power equal to 0.2930711 watts (W), the base unit for power. HVAC thermal rate (1 W ≈ 3.41214 BTU/hr). [2]

The btu per hour is classified as a US customary and imperial unit of power. BTU/hr can be abbreviated as BTU/hr; for example, 1 btu per hour can be written as 1 BTU/hr.

When working with btu/hr (BTU/hr) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.

In practice, btu/hr (BTU/hr) are widely used across standard power applications within US customary and imperial workflows, engineering documentation, and technical data sheets.

When converting power between kilowatts (kW) and btu/hr (BTU/hr), keep full floating-point precision (1 kW = 3,412.1416351 BTU/hr; 1 BTU/hr = 0.000293071 kW) during intermediate calculations and round only the final btu per hour figure to match your instrument tolerance.
