BTU/hr to Watts Converter

Convert heat transfer speed in BTUs per hour into physical power in watts.

How BTU/hr to Watts works

While a BTU measures total thermal energy, a BTU per hour (BTU/hr) measures the speed of thermal transfer (power). One BTU per hour is equivalent to approximately 0.293071 watts of power.

This conversion is common when sizing air conditioners or space heaters, where equipment cooling or heating capacity is quoted in BTUs, but electricity consumption is calculated in watts.

Formula

1W = BTU/hr × 0.293071

1 watt is equal to approximately 3.41214 BTU/hr.

FAQ: BTU/hr to Watts

How do you convert BTU/hr to watts?

Multiply the BTU/hr value by 0.293071. For example, a 10,000 BTU/hr AC unit has a thermal transfer power of 10,000 × 0.293071 = 2,930.71 Watts.

What does '1 Ton' of AC capacity mean in Watts?

One Ton of refrigeration capacity is defined as 12,000 BTU per hour. Converting this to power: 12,000 × 0.293071 = 3,516.9 Watts. This measures cooling capability, not the electrical draw of the compressor.
