What is the formula for HP to KW?
Electric Horsepower to Kilowatts Since one electric horsepower is equal to 0.746 kilowatts, the formula to find kilowatts is to multiply electric horsepower by 0.746.
What is KV and HP?
Electrical horsepower is a measure of power equivalent to 746 watts while kilovolt-amps measure apparent power. Because power factor and motor efficiency reduce the amount of actual work performed for the amount of apparent power in the circuit, the conversion from horsepower to kVA requires a formula.
Why is 1hp equal to 746 watts?
Theoretically, one horse power is defined as almost 746 Watt in standard calculations. It derived its name from the following context: One horsepower is the amount of power used by a horse to lift a 550 pounds heavy object from a depth of 1 foot in one second. This power when converted to SI system gives 746 Watts.
What watts mean?
powerA watt (W) is a unit of measurement of power. Watts therefore refer to the power of your device. Examples: an incandescent lamp has a power of 60 W. your microwave oven has a maximum power of 900 W.
Why is it called horsepower?
Horsepower dates back to the advent of the steam engine. Years ago, everything was driven by horses, but everything changed with the invention of the steam engine by James Watt. He needed a convenient way to sell his engines, so he came up with the measurement of horsepower.
Facts about kilowatt (kw)

Facts about horsepower (hp)
The horsepower (hp) is the name of several non-metric units of power. In scientific discourse the term "horsepower" is rarely used because of the various definitions and the existence of an SI unit for power, the watt (W).
What is a kilowatt?
Kilowatt. Definition: A kilowatt (symbol: kw) is a unit of power in the International System of Units (SI). The base unit of the kilowatt is the watt, which was named after Scottish inventor James Watt. As is consistent with SI units, the prefix kilo- means that a kilowatt equals one thousand watts or one thousand joules per second.
How many watts is one horsepower?
In addition, when rating electric motors, one horsepower is equal to 746 watts.
