How it works
- Type the value.
- Choose the unit you are converting from and the unit you want.
- Read the result, and scan the table for every other unit at once.
Horsepower
One mechanical horsepower is about 745.7 W. One metric horsepower (PS) is 735.5 W. They are close but not equal.
Heating and cooling
Air conditioners are often rated in BTU per hour or tons of refrigeration. One ton is 12,000 BTU/h, about 3.517 kW.
Power versus energy
Power is a rate. A 1 kW heater running for an hour uses 1 kWh of energy. Use the energy converter for that.
Large figures
Megawatts are included for power stations and large industrial plant.
