Formula

Formula
W = BTU/hr × 0.2930711

Multiply any value in British thermal units per hour by 0.2930711 to obtain the value in watts.

Worked example

Convert 10000 BTU/hr to W.

  1. 01Start with 10000 BTU/hr.
  2. 02Multiply by the conversion factor: 10000 × 0.2930711 = 2930.71 W.
Result10000 BTU/hr = 2930.71 W

FAQ

What is the conversion factor from BTU/hr to W?
1 BTU/hr equals 0.2930711 W. To convert, multiply the value in British thermal units per hour by 0.2930711.
How do I convert 1 BTU/hr to W?
1 BTU/hr = 0.293071 W. For any value, multiply by 0.2930711.
How do I convert W back to BTU/hr?
Divide by the same factor — or equivalently, multiply by 3.412142. So 1 W = 3.41214 BTU/hr.
When would I need to convert British thermal unit per hour to watt?
Power conversions are common when comparing motor ratings (often kW or hp), thermal duty (BTU/hr or kW), and utility consumption in mixed-unit projects.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
