Enter a value and pick its unit (Watts, kilowatts, horsepower, BTU/hr), and the tool converts it to every other power unit live.
1 mechanical horsepower = 745.7 watts; 1 metric horsepower (PS) = 735.5 watts.
Multiply kilowatts by 1.34102 to get mechanical horsepower.
BTU per hour rates the heating or cooling power of air conditioners and furnaces; 1 BTU/hr ≈ 0.293 watts.
