Power units
Power is the rate of energy use, measured in watts (SI), kilowatts and megawatts for larger loads, horsepower for engines, and BTU per hour for heating and air conditioning. One mechanical horsepower is about 745.7 watts. This converter links electrical, mechanical, and thermal power units in one place.
