About International table BTU per US gallon

The international table BTU per US gallon (BTU(IT)/gal(US)) equals 1055.05585262 J / 3.785411784 × 10⁻³ m³ ≈ 278716.27 J/m³. The dominant unit in the US petroleum and fuel markets for expressing heating values - gasoline ≈ 115,000 BTU/gal, diesel ≈ 129,500 BTU/gal. 1 BTU(IT)/gal(US) ≈ 278.72 kJ/m³.

About Megajoule per cubic metre

The megajoule per cubic metre (MJ/m³) equals exactly 10⁶ J/m³. The practical SI unit for fuel energy density: natural gas ≈ 35-40 MJ/m³, hydrogen (liquid) ≈ 8490 MJ/m³, diesel ≈ 34,200 MJ/m³. Numerically equal to kJ/L and widely used in fuel standards and energy audits. 1 MJ/m³ = 10⁶ J/m³ = 1 kJ/L.
