How to convert newton metres to inch-pounds
One newton metre equals 8.8508 inch-pounds, so multiply the number of newton metres by 8.8508:
in·lb = N·m × 8.8508
N·m = in·lb ÷ 8.8508 (1 in·lb = 0.112985 N·m)
Example: 5 N·m → 5 × 8.8508 = 44.2537 in·lb.
Going the other way, divide by 8.8508, or multiply by 0.112985; the inch-pounds to newton metres converter does it for you.
Everyday values
| Newton metres | Inch-pounds | For example |
|---|---|---|
| 1 N·m | 8.8508 in·lb | 1 N·m |
| 5 N·m | 44.2537 in·lb | a bicycle stem bolt, roughly |
| 10 N·m | 88.5075 in·lb | 10 N·m |
When you need this conversion
Multiply N·m by 8.851 to get inch-pounds. Many bicycle parts carry torque specs printed in N·m; torque wrenches in the US are often scaled in in·lb.

About the units
- Newton metre (N·m): the torque of 1 newton acting 1 metre from the axis.
- Inch-pound (in·lb): 1 pound-force acting 1 inch from the axis, 1/12 of a pound-foot.
Both are units of torque. The conversion factor comes from the exact definitions above, so the calculator is exact; results are only rounded for display (up to six significant digits).
