Inch-Pound to Newton-Meter Calculator

Convert inch-pound torque values into Newton-meters quickly and accurately. This torque conversion calculator supports engineering calculations, torque wrench settings, mechanical assembly, and rotational force measurements across Imperial and Metric systems.

What Are Inch-Pounds?

An inch-pound (in-lb) is an Imperial torque unit that measures rotational force produced when one pound of force acts at a distance of one inch from a pivot point. Automotive technicians, mechanical engineers, and equipment manufacturers use inch-pounds to define fastening torque, tightening torque, and torque wrench settings for precision assembly and maintenance applications.

What Are Newton-Meters?

A Newton-meter (N·m) is the SI unit of torque representing the rotational force generated when one Newton of force acts one meter from a rotational axis. Newton-meters are widely used in mechanical engineering, automotive torque specifications, aerospace systems, industrial equipment, and International System of Units (SI) documentation for standardized torque measurement.

Inch-Pound to Newton-Meter Formula

Use the standard torque conversion factor between Imperial and SI measurement systems to convert inch-pounds into Newton-meters accurately.

Practical Example Inch-Pound to Newton-Meter Conversions

Formula

$Nm = in\text{-}lb \times 0.112985$

Example

$50\ in\text{-}lb \times 0.112985 = 5.64925\ Nm$

$100\ in\text{-}lb \times 0.112985 = 11.2985\ Nm$

$250\ in\text{-}lb \times 0.112985 = 28.24625\ Nm$
