The formula for calculating wattage is: W (joules per second) = V (joules per coulomb) x A (coulombs per second) where W is watts, V is volts, and A is amperes of current. In practical terms, wattage is the power produced or used per second. For example, a 60-watt light bulb uses 60 joules per second.

Multiply the MWh figure from Step 1 by 8,760, the number of hours in a year. In this example, that would yield 87,600 MWh total annual power production. Divide the annual MWh figure from Step 2 by 1,000 to get GWh. Thus, 87,600 MWh/year equals 87.6 GWh/year.

1 kWh equals one hour of electricity usage at a rate of 1 kW, and thus the 2 kW appliance would consume 2 kWh in one hour, or 1 kWh in half an hour. The equation is simply kW x time = kWh.

A kilowatt-hour, expressed as kWh or kW·h, is a measure of energy that is equivalent to 1,000 watts of power for a 1 hour time period. Thus, to convert watts to kilowatt-hours, multiply the power in watts by the number of hours, then divide by 1,000. For example: let's find the kWh of 1,500 watts for 2.5 hours.

A kilowatt, also abbreviated kW, is a globally recognized standard for measuring electricity. One kilowatt is equal to 1,000 watts. Your electricity company charges by how much electricity you use per kilowatt hour (kWh). To put it simply, this means it measures the number of kilowatts you use over time.
