In-lbs to Nm Converter
Use our in-lbs to Nm converter to convert inch-pounds (in-lb) to newton-meters (N·m) instantly. Includes the in lb to nm conversion formula, how to convert in-lbs to Nm step by step, and torque examples for convert in lbs to nm torque.
In-lbs to Nm: How It Works
In-lbs to Nm conversion changes a torque value measured in inch-pounds (in-lb) into newton-meters (N·m). This is common in automotive, mechanical, and engineering work where torque specs may be listed in either Imperial or metric units.
If you’re searching “convert in lbs to nm,” “in lb to nm conversion,” or “in lbs to nm conversion calculator,” you’re looking for the same relationship: 1 in-lb equals 0.112984829 N·m (approximately 0.113 N·m).
Torque is the turning force applied around a محور/axis—like tightening a bolt with a torque wrench. Converting in-lbs to Nm helps you match the torque spec on your tool or spec sheet.
In-lb to Nm Conversion Formula
To convert inch-pounds to newton-meters, multiply by 0.112984829. To convert Nm back to in-lb, multiply by 8.85074579.
Round as needed (often to 2–3 decimals for torque specs).
Use this for reverse conversion.
So 10 in-lb is about 1.13 N·m.
So 25 in-lb is about 2.82 N·m.
So 100 in-lb is about 11.30 N·m.

Frequently Asked Questions
1 in-lb equals 0.112984829 N·m. Use Nm = in-lb × 0.112984829.
Multiply inch-pounds (in-lb) by 0.112984829 to get newton-meters (N·m).
In practice, people often write “in lbs” to mean inch-pounds. The standard notation is in-lb (inch-pound) to avoid confusion with inch-pounds vs inch-pounds-force.
Yes. Nm is a common shorthand for N·m (newton-meter).
Multiply by 0.113 for a fast estimate (since 0.112984829 ≈ 0.113).
