BTU Per Hour to Watts Converter
How to convert BTU per hour to watts
watts = BTU per hour ÷ 3.41214163
To convert BTU per hour to watts, divide the number of BTU per hour by 3.41214163.
1 BTU/h = 0.29307107 W
Examples
- One ton of refrigeration: 12,000 BTU/h ÷ 3.41214163 = 3,516.85284 W
- 5,000 BTU/h ÷ 3.41214163 = 1,465.35535 W
Good to know
One watt is about 3.412 BTU per hour. For air conditioners this converts cooling capacity, not the electricity consumed.
This uses the International Table BTU, 1055.05585262 J. Air conditioner and heater ratings quoted simply in "BTU" mean BTU per hour.
