用电度数怎么计算

To calculate electricity usage in kilowatt-hours (kWh), you can use the formula:

Electricity Usage (kWh) = Power (kW) x Time (hours)

For example, if you have a device with a power rating of 1.5 kW and you use it for 3 hours, the electricity usage would be:

Electricity Usage = 1.5 kW x 3 hours = 4.5 kWh

This calculation helps you determine how much electricity a device consumes over a specific period of time.
