Frequently asked questions
How many kW is 1 horsepower?
1 mechanical horsepower is about 0.7457 kW. 1 metric horsepower is about 0.7355 kW.
How many watts is a ton of refrigeration?
About 3,517 watts of cooling, which is 12,000 BTU per hour.
How many BTU per hour is 1 kW?
About 3,412 BTU per hour.
What is the difference between kW and kVA?
kW is real power, kVA is apparent power. kW = kVA × power factor, so a 100 kVA generator at a power factor of 0.8 delivers 80 kW.
