How to convert watts (W) to British Thermal Units per hour (BTU/hr).
One watt is equal to 3.412142 BTU per hour:
1 W = 3.412142 BTU/hr
The power in BTUIT per hour P(BTU/hr) is equal to 3.412142 times the power in watts P(W):
P(BTU/hr) = 3.412142 ⋅ P(W)
Convert 5000W to BTU/hr:
P(BTU/hr) = 3.412142 ⋅ 5000W = 17060.71 BTU/hr
