Kilojoules to gigajoule Conversion

1 kilojoules (kJ) is equal to 0.000001 gigajoule (GJ).

1 kJ = 0.000001 GJ

or

1 GJ = 1000000 kJ

Formula

To convert a energy from kilojoules (kJ) to gigajoule (GJ), divide the energy in kilojoules by 1000000

e(GJ) = e(kJ) / 1000000

Examples:

Convert 500 kilojoules to gigajoule:

e(GJ) = 500kJ / 1000000 = 0.0005 GJ
