About Megajoule and Foot-pound

The megajoule is one million joules. Fuel energy density, gas billing in some countries, and crash test energies are quoted in megajoules. The foot-pound is about 1.3558 joules — the work of one pound-force through one foot. US mechanical engineering and firearm muzzle energy use foot-pounds. One Megajoule equals 737562.1493 Foot-pound (1 MJ = 737562.1493 ft-lb). Megajoule to Foot-pound conversion comes up most often in fuel energy density figures and in natural gas billing, typically when figures need restating for US mechanical engineering.

Precision and Rounding: Energy factors mix exact definitions (1 kWh = 3,600,000 J; 1 cal = 4.184 J thermochemical) with measured conventions (1 BTU ≈ 1,055.056 J). Nutrition and utility bills round to whole units; engineering heat calculations should keep the full factor until the final step.

Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
