Foot-pounds (ft⋅lbs) and inch-pounds (in⋅lbs) are both units of torque, which measures the rotational force applied to an object. The main difference between these units is the distance at which the force is applied - feet versus inches.
| Foot-Pounds (ft⋅lbs) | Inch-Pounds (in⋅lbs) |
|---|---|
| 1 | 12 |
| 2 | 24 |
| 5 | 60 |
| 10 | 120 |
| 25 | 300 |
To convert between foot-pounds and inch-pounds, use these formulas:
Let's convert 25 foot-pounds to inch-pounds:
25 ft⋅lbs × 12 = 300 in⋅lbs
These torque measurements are commonly used in:
