Kilowatts to BTU/hr Converter

Convert kilowatts (kW) of power to British Thermal Units per hour (BTU/hr). One kilowatt is exactly 3,412.142 BTU/hr.

Kilowatt ↔ BTU per hour

Calculation Formula

1 kW × 3,412.14 = 3,412.14 BTU/hr

Worked Example

Convert 5 kW to BTU/hr: 5 kW × 3412.142 = 17,060.71 BTU/hr

Kilowatt to BTU per hour Table

Note: When looking at air conditioners or heat pumps, their BTU/hr cooling/heating capacity is NOT their electrical draw. A 12,000 BTU/hr air conditioner (approx 3.5 kW of thermal capacity) will typically only consume around 1 kW of electricity due to the coefficient of performance (COP).

Understanding the Conversion

This conversion finds the thermal equivalence of electrical power. It is commonly used when comparing electric resistive heating elements to gas heaters.

Compare heating & cooling costs.

Use your converted HVAC ratings to compare the running costs of heat pumps versus gas furnaces.
