Why this conversion matters in chemistry
US petroleum and natural-gas reports run in BTU and MMBTU; international fuel and refinery analysis uses MJ. The factor between them is exact through the IT-BTU definition: 1 BTU = 1055.06 J, so 1 MMBTU is 1055.06 MJ. A natural-gas heating value of 1030 BTU per standard cubic foot becomes about 1.087 MJ/scf when the same number lands on a metric process sheet. The conversion is decimal arithmetic, but it earns its keep at the boundary between US-tradition energy economics and SI-aligned fuel-chemistry reporting.
Formula
Worked Examples
One thousand BTU — about the energy of 1 MJ within rounding, useful as a quick mental conversion factor.
One BTU expressed in MJ — the per-unit factor that the rest of the table multiplies.
Exactly one megajoule expressed in BTU — the inverse anchor of the conversion.
One therm — the unit US natural-gas suppliers use for residential billing, equivalent to roughly 100 cubic feet of pipeline-quality natural gas.
