About Converting Decajoules to Foot-pounds
Decajoule 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: Decajoule is 10 joule units, and work from one pound-force over one foot.
Formula
foot-pounds = decajoules × 7.37562149277
This factor comes from each unit's defined relationship to the category's base unit: 1 decajoule equals 10 base units, and 1 foot-pound equals 1.35581794833 base units, so dividing one by the other gives the direct decajoule-to-foot-pound factor of 7.37562149277.
Simple example
1 daJ × 7.375621493 = 7.375621493 ft-lb
1 decajoule = 7.375621493 foot-pounds.
Real-world example
100 daJ × 7.375621493 = 737.5621493 ft-lb
100 decajoules = 737.5621493 foot-pounds.

How do I convert foot-pound back to decajoule?
Use the reverse factor: 1 foot-pound equals 0.1355817948 decajoules. You can also use the swap control in the converter above to flip the direction instantly.
What is a decajoule?
Decajoule (daJ) is a unit of engineering.
What is a foot-pound?
Foot-pound (ft-lb) is a unit of engineering.
Is the decajoule to foot-pound conversion exact?
Yes. Both decajoule and foot-pound are defined by fixed standards rather than physical artifacts, so the factor of 7.375621493 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.
