Formula
Ounce-inch (oz in) 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.
oz in relates to its own torque (rotational force) base unit by a factor of 0.00706155. ft-lb relates to its own energy base unit by a factor of 1.35582.
Conversion table
| Ounce-inch (oz in) | 0.00706155 × torque (rotational force) base unit |
| Foot-pound (ft-lb) | 1.35582 × energy base unit |

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