Kilowatts, MW and GW: Understanding Electricity Measurements
Convert kilowatts (kW) to gigawatts (GW) The formula for this conversion is P (GW) = P (kW)/1000000. This reads as the power in gigawatts is equal to the power in kilowatts divided by 1000000. Below is an example of how to use the formula: Let''s say we have 6000000 kilowatts we want to convert into gigawatts. P (GW) = 6000000/1000000 = 6 GW.
