Answer:
1 joule equals approximately 0.738 Ib-ft.
Step-by-step explanation:
To convert 1 joule into foot-pounds, we need to understand the relationship between these two units of energy. A joule is a unit of energy in the International System of Units (SI), while a foot-pound is a unit of energy commonly used in the United States, based on the imperial system.
1 joule is defined as the amount of energy expended in applying a force of 1 newton over a distance of 1 meter. On the other hand, 1 foot-pound is the energy expended in applying a force of 1 pound-force over a distance of 1 foot.
To convert joules to foot-pounds, we use the conversion factor between these two units. The conversion factor is based on the relationship between meters and feet, and newtons and pound-forces.
- 1 meter = 3.28084 feet
- 1 newton = 0.224809 pound-force
Using the conversion factors above we can find how many foot-pounds are in one joule:

Thus, 1 joule equals approximately 0.738 foot-pounds.
