Wattage, measured in watts (W), is the standard unit of power in the International System of Units (SI). It represents the rate of energy transfer or conversion per second. Named after James Watt—the same engineer who defined horsepower—a watt quantifies how much energy an electrical or ...
One metric horsepower is equal to 735.49875 watts:1 hp(M) = 735.49875 WSo the power conversion of horsepower to watts is given by:P(W) = 735.49875 ⋅ P(hp)ExampleConvert 10 hp to watts:P(W) = 735.49875 ⋅ 10hp = 7354.9875 W...
1 horsepower (over the course of an hour) is equivalent to 2,545 BTU (British thermal units). If you took that 746 watts and ran it through an electric heater for an hour, it would produce 2,545 BTU (where a BTU is the amount of energy needed to raise the temperature of 1 pound...
A watt is a unit of power (1 horsepower = 746 watts), whereas watt-hours tell you how much energy is used over a period of time. For example, a 100-watt light bulb uses twice as much power at any given moment as a 50-watt bulb. To find out how much electricity that light bulb...
1 Horsepower (HP): Equal to 746 watts Average desktop PC: Requires about 0.27 horsepower to operate. Even if we account for the generator's efficiency, which is likely less than 100 percent, it still means a regular Joe would need to generate around a third of a horsepower. ...
1 dyne = 10−5newtons 1 erg = 10−7joules You can also express your result in kilowatts (kw). The kilowatt formula is 1 kw = 1,000 watts. Watts as Units of Electrical Power The power formula for a circuit with a voltage V and current I is ...
Horsepower: Sump pumps are commonly one-quarter to one-third horsepower. More powerful motors will pump more water, but you don't need to go overboard if your moisture problem is minor. Head pressure: Head pressure is the height a pump can raise water. For example, a pump with head press...
