Converter Watts to HP
Please provide values below to convert watt [W] to horsepower (metric), or vice versa.
A watt (Symbol: W) is the SI (International System of Units) derived unit of power. It is defined as 1 joule per second and is used to quantify the rate of energy transfer.
The unit horsepower (symbol: hp) is a unit of measurement of power (the rate at which work is done). Mechanical horsepower, also known as imperial horsepower, is defined as approximately 745.7 watts (550 ft·lbf/s), while metric horsepower is approximately 735.5 watts (75 kgf·m/s). Boiler horsepower, albeit a less common measurement than either imperial or metric horsepower, is used for rating steam boilers, and is equivalent to 34.5 pounds of water evaporated per hour at 212 degrees Fahrenheit, or 9809.5 watts. In addition, when rating electric motors, one horsepower is equal to 746 watts.
