How to Use This Calculator
Enter the torque in N·m
Use torque values derived from SI specs, CAD outputs, or testing equipment.
Review inch-pound torque
The calculator multiplies by 8.85074579 to convert N·m to lb·in.
Check related imperial units
Foot-pounds and inch-ounces are shown automatically for bolt standards, firearm work, and precision tools.
Formula
lb·in = N·m × 8.85074579
Derived from 1 N·m = 0.737562149 lb·ft and 1 lb·ft = 12 lb·in. Inch-ounces multiply inch-pounds by 16.
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Inch-pounds are the go-to torque unit for smaller fasteners, woodworking, and precision devices. This converter bridges the gap between SI torque data and the imperial units used on torque screwdrivers, firearms, and assembly tooling.
Foot-pound and inch-ounce outputs are provided automatically, streamlining cross-unit comparisons without manual recalculations or separate tools.
For reverse conversions, use the Inch-Lbs to Nm Converter; for higher torque ranges, the Nm to Ft-Lbs Converter keeps automotive and industrial specs aligned.
Frequently Asked Questions
Why is the conversion factor 8.85074579?
It reflects the exact SI-to-imperial relationship between meters and inches, and newtons and pounds-force, ensuring precise conversions.
Can I convert small torques?
Yes. The converter handles fractions of a newton-meter, which is useful for electronics and instrument fasteners.
Does the calculator keep the sign?
Negative torque inputs are preserved in the outputs to signify direction or opposite tightening.
What about torque per degree?
This tool focuses on unit conversions. For torque-angle analysis, pair it with mechanical design software or spreadsheets.
