Watt-hour to gigajoule Conversion

1 watt-hour (W⋅hr) is equal to 0.0000036 gigajoule (GJ).

1 W⋅hr = 0.0000036 GJ

1 GJ = 277777.7778 W⋅hr

Formula

To convert a energy from watt-hour (W⋅hr) to gigajoule (GJ), divide the energy in watt-hour by 277777.7778

e_(GJ) = e_(W⋅hr) / 277777.7778

Examples:

Convert 100 watt-hour to gigajoule:

e_(GJ) = 100W⋅hr / 277777.7778 = 0.00036 GJ
