An electrical equipment for 30 w, how to calculate how many kilowatts of electricity it uses in a month

First, we need to determine whether this equipment is working continuously 24 hours a day, if so, we can calculate the daily power consumption according to the continuous work, and then calculate the monthly power consumption according to the number of days in the month.

Based on the formula for electricity: 1KWH = 1 kWh

Power consumption per day (24h): 30×24/1000 = 0.72 kWh

Power consumption in February (28 days): 0.72×28 = 20.06 kWh

Power consumption in a small month (30 days): 0.72×30 = 21.6 kWh

Big month (31 days): 0.72×30 = 21.6 kWh

This is the first time that we have to determine whether the equipment works continuously every day. p>Large month (31 days) power consumption: 0.72 × 31 = 22.32 kWh

By this number of statistics of the month's electricity consumption is, large and small months are clearly distinguishable.
