BTU (British Thermal Unit) and BTU per hour (BTU/hr) are different units of measurement. A BTU measures the amount of energy needed to raise the temperature of one pound of water by one degree Fahrenheit, while BTU/hr indicates the rate at which energy is used or transferred. Therefore, BTU/hr quantifies BTUs over time, not a direct conversion. For example, if a heater provides 5,000 BTU/hr, it delivers 5,000 BTUs of heat energy every hour.
The output rating of a 96% efficient boiler or furnace rated at 100,000 input.
1kW is 3,412.13 BTU/hr
65,000 BTU per hour equates to 19.05 kW
12,000 BTU/hr
Almost 340,000 BTU per hr
4600 BTU/hr is 1.3481268kW
14,500 BTU/hr is 4.25kW
35kW is 119,424.97 BTU/hr
2.25HP is 5,724.95 BTU/hr
34kW is 116,012.828 BTU/hr
70000 BTU/hr = 20.5kW > 70000 BTU/min = 1230.9kW > 70000 BTU/sec = 73854.2kW
1 cal/day*0.003968321 Btu/cal *1day/24hr = 0.003968321/24 = 0.000165347 Btu/hr
