Gigawatt-hour to kilowatt-hours Conversion
1 gigawatt-hour (GW⋅hr) is equal to 1000000 kilowatt-hours (kWh).
1 GW⋅hr = 1000000 kWh
or
1 kWh = 0.000001 GW⋅hr
Formula
To convert a energy from gigawatt-hour (GW⋅hr) to kilowatt-hours (kWh), multiply the energy in gigawatt-hour by 1000000
e(kWh) = e(GW⋅hr) × 1000000
Examples:
Convert 100 gigawatt-hour to kilowatt-hours:
e(kWh) = 100GW⋅hr × 1000000 = 100000000 kWh
