Kilowatt is that mathematical conversion of kWh/hour, kilowatt is the unit of electric pow, kilowatt-hour is the unit of electric energy, which can be converted by joule.

The power of an electrical appliance is 3 kilowatts, which is the amount of electricity it consumes per unit time! Refers to the consumption of 3 kWh per hour (commonly known as 3 kWh).

Extended data:

Unit conversion of one kilowatt hour:

One kWh is equal to: 3.595438+02× 10 Joule.

One kwh is equal to: 1.355438+0 12 meter horsepower hour.

One kWh is equal to: 1.34927 British horsepower hours.

The first degree of electricity is equal to: 8.595438+02023× 10? One thousand calories.

The first degree of electricity is equal to: 3.4 1 1× 10? British unit of heat.

Electric work (w) is the same as electric energy. The international unit is joule (j).

The formula of electric power: P=W/t (in the formula, t stands for time, the basic unit is second -s, and it is often calculated in unit hour -h).

Measurement formula of electric power: P=UI (where u stands for voltage, and the basic unit is volt-v; Capital I stands for current, and the basic unit is ampere -A)

According to ohm's law: U=IR (where R stands for resistance and the basic unit is ohm-ω).
