How to Use This Calculator
Enter the torque in inch-pounds
Use torque values from datasheets, torque wrenches, or fastener charts.
Review the newton-meter result
The converter computes N·m instantly, ensuring compliance with SI specifications.
Copy alternate units if needed
Foot-pound and inch-ounce outputs help when working with multiple torque standards.
Formula
N·m = lb·in × 0.1129848290
Derived from 1 lbf = 4.4482216152605 N and 1 in = 0.0254 m. Foot-pound conversion uses 1 lb·ft = 12 lb·in.
Use the formula breakdown to confirm the calculation logic or perform the conversion manually if needed.
Full Description
Inch-pounds (lb·in) are common in manufacturing, gunsmithing, and electronics assembly. When collaborating with international teams or following ISO requirements, torque values often need to be expressed in newton-meters. This converter bridges that gap instantly.
Additional outputs in foot-pounds and inch-ounces let you compare torque limits across different tool families and fastener specifications without manually re-running calculations.
For reverse conversions, use the Nm to in-lbs Converter or Nm to ft-lbs Converter so your torque data stays consistent throughout documentation.
Frequently Asked Questions
Why would I use inch-pounds instead of foot-pounds?
Inch-pounds offer finer resolution for small fasteners and assemblies. Twelve inch-pounds equal one foot-pound.
Can I enter decimal inch-pounds?
Yes. Torque wrenches and specs often list decimal values. The converter maintains precision in the outputs.
Does this handle negative torque?
Negative values represent reverse torque or tensioning in the opposite direction. The conversion preserves the sign.
How accurate is the constant?
The converter uses the exact SI definitions, providing N·m values precise enough for engineering and calibration work.
