How to convert watts to BTU per hour
Power is energy transferred per time: 1 W = 1 J/s. Mechanical, metric and electrical horsepower have different definitions; select the version stated on the equipment rating.
BTU/h = W ÷ 0.2930710702One BTU per hour corresponds to 0.2930710702 watts, so divide by that figure. Displayed constants may be rounded; the converter uses the stored factor before rounding the result.

Sources and precision
Table results are rounded to 8 significant digits; formula constants may be rounded to 10. Worked example answers use 6 significant digits. The converter starts at 6 significant digits and lets you change display precision. Calculations use the stored factors without intermediate rounding. Exact unit definitions do not make an input measurement more precise; conventional and measured factors follow the assumptions stated here.
