How the conversion works
Multiply by 947.8171203 to go from megajoule to British thermal unit, or divide by it to go back. Every conversion on this site routes through the SI value (J) rather than a table of pairwise factors, so a round-trip returns exactly what you started with.
Going the other way? British thermal unit to megajoule — 1 BTU = 0.001055055853 MJ.
