Power Converter
What this does
Converts power: watt, kilowatt, megawatt, horsepower (mechanical and metric), BTU per hour and foot-pounds per second.
Handy anchors
- 1 hp = 745.7 W; 1 metric hp (PS) = 735.5 W. 1 kW = 1.34 hp.
- A 12,000 BTU/h air conditioner is 3.5 kW of cooling.
Good to know
Power is a rate. Multiply by time to get energy — a 2 kW heater for 3 hours uses 6 kWh.
