How to calculate power consumption？ What is the formula for calculating power consumption？

Calculation method of electrical appliances’ power consumption: No matter what kind of electrical appliances are, the power (watts, represented by the letter W) will be marked on the manual or nameplate. Usually, what kind of kilowatt-hour is what we call the power consumption, and the concept is the power consumed by an electrical appliance with a power of 1000(W) in one hour.

In this question, W=P*T, where w is work, that is, the consumed electric energy; P is power; T is time. 350W*1h=350wh=0.35Kwh=0.35 degrees.

Calculation formula: 1KW×1 1h =1 kwh, 350w ÷ 1000w = 0.35kw × 1h =0.35KWH (kwh).
