British thermal units to megajoule Conversion
1 British thermal units (BTU) is equal to 0.001055055853 megajoule (MJ).
1 BTU = 0.001055055853 MJ
or
1 MJ = 947.8171203 BTU
Formula
To convert a energy from British thermal units (BTU) to megajoule (MJ), divide the energy in British thermal units by 947.8171203
e(MJ) = e(BTU) / 947.8171203
Examples:
Convert 1000 British thermal units to megajoule:
e(MJ) = 1000BTU / 947.8171203 = 1.055055853 MJ
