About Converting Megajoules to Foot-pounds
Megajoule and Foot-pound both measure a quantity used in structural or mechanical engineering — commonly stress, pressure, force, torque, power, or energy — where converting between the unit conventions used in different regions, industries, or equipment specifications is a routine part of design work. Specifically: Megajoule is 1000000 joule units, and work from one pound-force over one foot.
Formula
foot-pounds = megajoules × 737562.149277
This factor comes from each unit's defined relationship to the category's base unit: 1 megajoule equals 1000000 base units, and 1 foot-pound equals 1.35581794833 base units, so dividing one by the other gives the direct megajoule-to-foot-pound factor of 737562.149277.
Simple example
1 MJ × 737562.1493 = 737,562.1493 ft-lb
1 megajoule = 737,562.1493 foot-pounds.
Real-world example
100 MJ × 737562.1493 = 73,756,214.93 ft-lb
100 megajoules = 73,756,214.93 foot-pounds.

How do I convert foot-pound back to megajoule?
Use the reverse factor: 1 foot-pound equals 0.0000013558 megajoules. You can also use the swap control in the converter above to flip the direction instantly.
What is a megajoule?
Megajoule (MJ) is a unit of engineering.
What is a foot-pound?
Foot-pound (ft-lb) is a unit of engineering.
Is the megajoule to foot-pound conversion exact?
Yes. Both megajoule and foot-pound are defined by fixed standards rather than physical artifacts, so the factor of 737562.1493 used above is exact to as many digits as you choose to display.
Why do engineering unit conventions vary so much by region and industry?
Pressure, force, and stress can be expressed in metric (pascal, newton), US customary (psi, pound-force), or older and industry-specific units (atmosphere, torr, kip) depending on the country, industry, and even the equipment manufacturer, which is why engineers routinely need to convert between them when working across specs from different sources.
