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

Formula
Kilonewton meter (kN 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.
kN m relates to its own torque (rotational force) base unit by a factor of 1000. ft-lb relates to its own energy base unit by a factor of 1.35582.
Conversion table
| Kilonewton meter (kN m) | 1000 × torque (rotational force) base unit |
| Foot-pound (ft-lb) | 1.35582 × energy base unit |

Frequently asked questions
Can Kilonewton meter be converted to Foot-pound?
Not directly. Kilonewton 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 Kilonewton meter used for?
The Kilonewton meter (kN m) is a unit of torque (rotational force). Kilonewton meter is 1000 newton meter units.
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 Kilonewton meter and Foot-pound don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Kilonewton meter to instead?
Use another torque (rotational force) unit, such as one of the related Kilonewton 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 Kilonewton meter (kN m) and Foot-pound (ft-lb) within the engineering converter.
Kilonewton meter is 1000 newton meter units. Work from one pound-force over one foot.
Because Kilonewton 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.
