AC Watt/DC Watt A watt is a unit of power that measures the rate of energy transfer or usage. A kilowatt is equal to 1,000 watts. A kilowatt hour is the amount of electricity used. To calculate the amount an appliance uses in kilowatt hours, take its wattage, multiply it by the number of hours you use it, and divide by 1,000.If you take a 100-watt light bulb and use it for 540 hours, the light bulb will use 54 kWh of electricity.f you look at your power bill, you will see your monthly kilowatt hour usage. This is how much electricity you used for that month and were charged for. Normally your power company will bill you based on a rate per kWh. Sometimes this rate varies depending on the time of day or your usage.

Power (physics) In physics, power is the rate of doing work, the amount of energy transferred per unit time. Having no direction, it is a scalar quantity. In the International System of Units, the unit of power is the joule per second, known as the watt in honour of James Watt, the eighteenth-century developer of the steam engine condenser. Another common and traditional measure is horsepower. Being the rate of work, the equation for power can be written: power = work time {\displaystyle {\text{power}}={\frac {
