How to Convert Joules to Foot-Pounds
A joule is the SI unit of energy, defined as 1 newton-meter, while a foot-pound is an imperial unit representing the energy needed to apply one pound of force over a distance of one foot. 1 joule (J) = 0.737562149 foot-pounds (ft·lbf), so multiply joules by 0.737562149 to convert to foot-pounds.
Formula
Quick Trick: 1 Joule = 0.73756 foot-pounds!
Let’s Solve One Together
Imagine you have an energy measurement:
- We measured: 500 joules
Here’s how we figure it out:
1. Take our formula: ft·lb = J × 0.73756
2. Put in 500 joules
3. ft·lb = 500 × 0.73756
Answer: 368.78 ft·lb
Definitions of Key Terms
Foot-Pound (ft·lb)
A foot-pound (ft·lb) measures the work done when a force of one pound moves an object one foot. It is commonly used in mechanical engineering to quantify work and energy in various applications.
Joules (J)
The joule is the standard unit of energy in the International System of Units (SI). It represents the energy transferred when a force of one newton moves an object one meter. Joules are widely used in physics and engineering to measure energy, work, and heat.
