How to Convert BTU/hr to Watts
To convert btu/hr to watts, multiply the power by the following conversion ratio: 0.2930711 watts/btu per hour.
Since one btu per hour is equal to 0.2930711 watts, you can use this simple formula to convert:
The power in watts is equal to the power in btu/hr multiplied by 0.2930711.
For example, here's how to convert 12000 btu/hr to watts using the formula above.
How Many Watts Are in a BTU per Hour?
There are 0.2930711 watts in a btu per hour, which is why we use this value in the formula above.

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 Watt?
Coherent SI unit of power equal to 1 Joule per second (1 J/s). It serves as a primary reference unit for measuring power across scientific and practical applications. [2]
The watt is classified as an International System of Units (SI) unit of power. Watts can be abbreviated as W; for example, 1 watt can be written as 1 W.
As the primary coherent reference unit for power in this category, all other power units are mathematically anchored to the watt (W).
In practice, watts (W) are widely used across standard power applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting power between btu/hr (BTU/hr) and watts (W), keep full floating-point precision (1 BTU/hr = 0.2930711 W; 1 W = 3.4121416 BTU/hr) during intermediate calculations and round only the final watt figure to match your instrument tolerance.
