Foot-pounds (ft⋅lb) and Newton-meters (N⋅m) are both units of torque or moment of force. Torque is a measure of the rotational force applied to an object. These units are commonly used in mechanical engineering, automotive applications, and various industrial settings.
To convert between foot-pounds and Newton-meters, use the following formula:
1 foot-pound (ft⋅lb) = 1.355818 Newton-meters (N⋅m)
1 Newton-meter (N⋅m) = 0.737562 foot-pounds (ft⋅lb)
| Foot-Pounds (ft⋅lb) | Newton-Meters (N⋅m) |
|---|---|
| 1 | 1.36 |
| 5 | 6.78 |
| 10 | 13.56 |
| 25 | 33.90 |
| 50 | 67.79 |
| 100 | 135.58 |
Let's walk through an example of converting 75 foot-pounds to Newton-meters:
1. Take the value in foot-pounds: 75 ft⋅lb
2. Multiply by the conversion factor: 75 × 1.355818
3. Result: 75 ft⋅lb = 101.69 N⋅m
These torque units are frequently used in:
• Automotive maintenance (engine specifications, lug nut torque)
• Industrial equipment calibration
• Construction equipment specifications
• Engineering calculations and designs
• Manufacturing quality control
