Context values
Some unit families need one extra value for a physically accurate result.

Formula
Newton meter (N m) measures torque (rotational force), while Foot-pound (ft-lb) measures energy. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
N m relates to its own torque (rotational force) base unit by a factor of 1. ft-lb relates to its own energy base unit by a factor of 1.35582.
Conversion table
| Newton meter (N m) | 1 × torque (rotational force) base unit |
| Foot-pound (ft-lb) | 1.35582 × energy base unit |

Frequently asked questions
Can Newton meter be converted to Foot-pound?
Not directly. Newton meter measures torque (rotational force) and Foot-pound measures energy. Converting between different physical quantities needs an extra physical relationship (such as area, distance, or time), not just a unit ratio.
What is Newton meter used for?
The Newton meter (N m) is a unit of torque (rotational force). Newton meter is the SI torque unit.
What is Foot-pound used for?
The Foot-pound (ft-lb) is a unit of energy. Work from one pound-force over one foot.
Why does the converter show an incompatible units message?
The Universal Converter only calculates a numeric result when both units share the same physical dimension. Since Newton meter and Foot-pound don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Newton meter to instead?
Use another torque (rotational force) unit, such as one of the related Newton meter conversions linked below.
What should I convert Foot-pound to instead?
Use another energy unit, such as one of the related Foot-pound conversions linked below.

About this conversion
This page compares Newton meter (N m) and Foot-pound (ft-lb) within the engineering converter.
Newton meter is the SI torque unit. Work from one pound-force over one foot.
Because Newton meter measures torque (rotational force) and Foot-pound measures energy, the two units are not directly convertible: there is no fixed ratio that turns one into the other without additional information.
The calculator above will report that these units are not compatible. For a working result, choose two units from the same measurement family — see the related conversions below.
