Power Converter

BTU (SI)/hour

In the field of HVAC, BTU/h is a commonly used unit to measure equipment power or heat load. For example, the cooling capacity of an air conditioner may be 10000 BTU/h, approximately 2.93 kW.

1BTU (thermo)/hour≈0.293W

1 BTU(thermo)/hr = 1055.06 joules/hour.

BTU (thermo)/hour

BTU stands for British Thermal Unit (imperial unit), and BTU/h means "British Thermal Units per hour." BTU/hr is an imperial unit of heat, and its full name is British Thermal Unit per Hour, which refers to the amount of heat dissipated per hour.

The conversion relationship between BTU/hr and the traditional unit of Watt (W) is as follows: 

1 BTU/hr = 0.02 BTU (thermo)/minute

1 00BTU/hr = 0.03 BTU (thermo)/second

1 BTU/hr = 4.2 Calorie (thermo)/minute

1 BTU/hr = 0.07 Calorie (thermo)/second

1 BTU/hr = 2928751 Erg/second

1 BTU/hr = 777.65 Foot-pound force/hour

1 BTU/hr = 12.96 Foot-pound force/minute

1 BTU/hr = 0.22 Foot-pound force/second

100BTU/hr =  0.04 Horsepower (UK)

1000BTU/hr = 0.03 Horsepower (boiler)

1.67 joules per second  
The conversion relationship between Calorie (Thermo)/minute and joules/second is: 

1 Calorie (Thermo)/minute=1.67 joules/second  
1 calorie (heat)/minute=1.67 joules/second  
1 kilojoule/second=1000 joules/second  
1 joule/second=0.001 kilojoules/second
