Frequently asked questions
What is the source unit in this conversion?
The source unit is the Pound-inch (lb in). Torque from one pound-force at one inch.
What is the destination unit in this conversion?
The destination unit is the Newton meter (N m). Newton meter is the SI torque unit.
How do I convert Pound-inch to Newton meter?
Multiply the Pound-inch value by 0.112985. For example, 10 lb in × 0.112985 = 1.12985 N m.
Is the Pound-inch to Newton meter conversion exact?
Yes. Both units belong to the same engineering measurement family (torque (rotational force)), so the ratio between them is a fixed, defined value rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in Pound-inch needs to be compared with, or reported in, Newton meter, such as in engineering, scientific, or industrial calculations.
Can I convert Newton meter back to Pound-inch?
Yes. Multiply the Newton meter value by 8.85075 to get Pound-inch.

About this conversion
This page converts Pound-inch (lb in) to Newton meter (N m) within the engineering converter.
Torque from one pound-force at one inch. Newton meter is the SI torque unit.
The formula is N m = lb in × 0.112985, based on each unit's fixed relationship to the torque (rotational force) base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
