  1. 1 BTU/h = 0.293071070172 W
  2. 1 × 0.293071070172 = 0.293071070172 W

How to convert btu (it) per hour to watts

1 BTU/h = 0.293071070172 W, so multiply by 0.293071070172 to go from BTU (IT) per hour to watts. Going the other way, 1 W = 3.41214163313 BTU/h.

W = BTU/h × 0.293071070172
BTU/h = W × 3.41214163313

Worked example:

1 BTU/h = 0.293071070172 W
5 × 0.293071070172 = 1.46535535086 W
