Nm to In-Lbs Converter
Convert a torque value from newton-meters (Nm) to inch-pounds (in-lb) using the standard SI-to-imperial conversion factor.
What This Calculator Does
This tool converts a torque measurement from newton-meters (Nm), the standard SI unit, into inch-pounds (in-lb), a common imperial unit used for smaller fasteners, bicycle components, and many hand-tool torque wrenches sold in the US.
The Formula
The conversion uses the fixed, internationally accepted factor:
- Inch-pounds = Newton-meters × 8.85074579
- For reference, foot-pounds = Newton-meters × 0.737562149
These factors come directly from the definitions of the newton, meter, pound-force, and inch, so the result is exact (rounded for display) rather than an approximation.
When to Use It
Torque specifications for small bolts, electronics enclosures, bicycle parts, and many consumer products are often given in inch-pounds, while automotive and industrial specs frequently use newton-meters or foot-pounds. Use this calculator to quickly cross-check a spec sheet or torque wrench setting. This tool is for general reference and educational purposes only; always follow the exact torque values and tolerances given in a manufacturer’s official documentation for critical or safety-related applications.
