Context values
Some unit families need one extra value for a physically accurate result.
Use the converter to see the formula.
Kilogram-force and Pound-foot measure different quantities, so no single result applies.
Reserved above the conversion cards and below the converter.
Formula
Kilogram-force (kgf) measures force, while Pound-foot (lb ft) measures torque (rotational force). These are different physical quantities, so there is no single multiplication factor that converts one into the other.
kgf relates to its own force base unit by a factor of 9.80665. lb ft relates to its own torque (rotational force) base unit by a factor of 1.35582.
Conversion table
| Kilogram-force (kgf) | 9.80665 × force base unit |
| Pound-foot (lb ft) | 1.35582 × torque (rotational force) base unit |

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

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