How to Convert BTU/hr to Kilowatts
To convert btu/hr to kilowatts, multiply the power by the following conversion ratio: 0.000293071 kilowatts/btu per hour.
Since one btu per hour is equal to 0.000293071 kilowatts, you can use this simple formula to convert:
The power in kilowatts is equal to the power in btu/hr multiplied by 0.000293071.
For example, here's how to convert 5 btu/hr to kilowatts using the formula above.
How Many Kilowatts Are in a BTU per Hour?
There are 0.000293071 kilowatts in a btu per hour, which is why we use this value in the formula above.
Our btu per hour to kilowatt calculator automatically converts your power measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
BTU/hr and kilowatts are both units used to measure power. Keep reading to learn more about each unit.
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). [1]
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.
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). [2]
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.
When converting power between btu/hr (BTU/hr) and kilowatts (kW), keep full floating-point precision (1 BTU/hr = 0.000293071 kW; 1 kW = 3,412.1416351 BTU/hr) during intermediate calculations and round only the final kilowatt figure to match your instrument tolerance.
