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

Formula
Pound-foot (lb ft) measures torque (rotational force), while Kilogram-force (kgf) measures force. These are different physical quantities, so there is no single multiplication factor that converts one into the other.
lb ft relates to its own torque (rotational force) base unit by a factor of 1.35582. kgf relates to its own force base unit by a factor of 9.80665.
Conversion table
| Pound-foot (lb ft) | 1.35582 × torque (rotational force) base unit |
| Kilogram-force (kgf) | 9.80665 × force base unit |

Frequently asked questions
Can Pound-foot be converted to Kilogram-force?
Not directly. Pound-foot measures torque (rotational force) and Kilogram-force measures force. Converting between different physical quantities needs an extra physical relationship (such as area, distance, or time), not just a unit ratio.
What is Pound-foot used for?
The Pound-foot (lb ft) is a unit of torque (rotational force). Torque from one pound-force at one foot.
What is Kilogram-force used for?
The Kilogram-force (kgf) is a unit of force. Kilogram-force under standard gravity.
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 Pound-foot and Kilogram-force don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Pound-foot to instead?
Use another torque (rotational force) unit, such as one of the related Pound-foot conversions linked below.
What should I convert Kilogram-force to instead?
Use another force unit, such as one of the related Kilogram-force conversions linked below.

About this conversion
This page compares Pound-foot (lb ft) and Kilogram-force (kgf) within the engineering converter.
Torque from one pound-force at one foot. Kilogram-force under standard gravity.
Because Pound-foot measures torque (rotational force) and Kilogram-force measures force, 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.
