The power of electric kettle is generally 1500~ 1800w, and the water will boil in about 5 minutes. Calculated by1800W for 5 minutes,1.8kw× 5 ÷ 60 = 0.15kwh = 0.15 degrees.

One degree of electricity = 1000 watt/hour.

The average pot is 500 to 1000 watts, that is, 500 watts is burned for two hours, and 1000 watts is used for one hour. The size of the specific pot varies from pot to pot.
