N·m to in·lb Calculator — Newton-Meters to Inch-Pounds Torque Converter
Convert any torque value between Newton-meters and inch-pounds (in both directions). Inch-pounds are the standard for small fasteners in electronics, bicycles, motorcycles, and precision equipment where foot-pounds would be too coarse.
Conversion direction
N·m
1 N·m ≈ 8.8507 in·lb • 1 in·lb ≈ 0.1130 N·m
- 1
Conversion factor
1 N·m = 8.850746 in·lb = 8.8507461 in·lb = 1 ft·lb ÷ 12; inverse gives 8.8507 in·lb per N·m. - 2
Result in inch-pounds
10 × 8.850746 = 88.5075
How does this calculator work?
1 N·m ≈ 8.8507 in·lb; 1 in·lb ≈ 0.11298 N·m; 1 ft·lb = 12 in·lb. Inch-pounds are standard for small fasteners in bicycles, motorcycles, and electronics. To convert N·m → in·lb multiply by 8.8507; to go back multiply by 0.11298.
Formula
How this is calculated
An inch-pound (in·lb) is a unit of torque equal to one pound-force (lbf ≈ 4.44822 N) acting at a distance of one inch (0.0254 m) from the pivot. Because 1 foot = 12 inches, one inch-pound is exactly 1/12 of a foot-pound, and therefore 1/12 × 1.3558179 N·m ≈ 0.11298 N·m. Conversely, 1 N·m ≈ 8.8507 in·lb.
Inch-pounds are preferred when working with small fasteners — M3–M6 bolts, carbon-fibre bicycle components, electronics chassis screws, or fuel-injector clamps — where the torque values are typically in the range of 5–100 in·lb (≈ 0.5–11 N·m). Many torque wrenches for bicycle mechanics and electronics repair are calibrated in inch-pounds. Workshop manuals for motorcycles and small engines also commonly list values in in·lb for sub-frame fasteners and cover bolts.
All conversions in this calculator derive from the exact international definitions of the pound-force and inch, so they are fully symmetric: converting a value from N·m to in·lb and back gives exactly the original number.
Frequently asked questions
Multiply by 8.8507. For example, 5 N·m = 5 × 8.8507 ≈ 44.25 in·lb. This is the conversion needed when a workshop manual gives torque in N·m but your torque wrench reads in in·lb.
Multiply by 0.11298. For example, 50 in·lb = 50 × 0.11298 ≈ 5.65 N·m. Torque wrenches for bicycle or electronic work often read in in·lb; this gives the SI equivalent.
Both are US customary torque units. One foot-pound (ft·lb) equals exactly 12 inch-pounds (in·lb). Foot-pounds are used for larger fasteners (lug nuts, cylinder heads, suspension bolts) while inch-pounds apply to small fasteners where foot-pounds would be too large to specify accurately.
