BTU/h to WattsBTU/h → W
1 BTU/h = 0.293071 W · 1 W = 3.41214 BTU/h
Formula
W ≈ BTU/h ÷ 3.41214
Example: 12,000 BTU/h = 12,000 ÷ 3.41214 = 3,516.85 W
These units differ only by a fixed factor: multiply by it to convert, divide to go back. The factors are exact international definitions (for example 1 inch = 2.54 cm exactly); results are rounded only for display.
