Watts to BTU/h: Convert watts to BTU per hour

Answer
3.41214 BTU/h = 1 W

1 W = 3.41214 BTU/h. To convert watts to BTU per hour, multiply by 3.412141633. To go back, multiply by 0.2930710702 (or divide by 3.412141633). Watts measure electrical power; heating and cooling equipment is often sized in BTU/h instead.
