Electric Power
What is electric power?
Measuring Electric Power
Unit Conversions
Despite the fact that power is commonly measured in watts, one watt is a modest amount of electric energy. When assessing the cost of power, watts are usually converted to kilowatts (kW). This is done by multiplying the supplied number of watts by 1000.
1000 W = 1 kW
W -> divide by 100 -> kW
3450.5 W = 3.4505 kW
