The work done by converting electric energy to other energy electricity is called electric work, expressed in W, and its expression is:

W=UIt formula, U - voltage applied to both ends of electrical equipment (unit: V);

I -- Current passing through electric equipment (unit: A);

T -- Power consumption time of electric equipment (unit: S).

The unit of practical time is usually expressed in hours (h), so watt hour can also be expressed in watt hours (Wh). One degree of electricity on the watt hour meter is 1000Wh, while "thousand" is often expressed in k, so it can be written as 1kWh. For example, the power consumption of a 100 watt lamp for 10 hours is W=100 × 10=1000 watt hours=1 kWh.
