British thermal units to gigajoule Conversion
1 British thermal units (BTU) is equal to 0.000001055055853 gigajoule (GJ).
1 BTU = 0.000001055055853 GJ
or
1 GJ = 947817.1203 BTU
Formula
To convert a energy from British thermal units (BTU) to gigajoule (GJ), divide the energy in British thermal units by 947817.1203
e(GJ) = e(BTU) / 947817.1203
Examples:
Convert 100 British thermal units to gigajoule:
e(GJ) = 100BTU / 947817.1203 = 0.0001055055853 GJ
