Context values
Some unit families need one extra value for a physically accurate result.
Use the converter to see the formula.
Atmosphere and Pound-foot measure different quantities, so no single result applies.
Reserved above the conversion cards and below the converter.
Formula
Atmosphere (atm) measures pressure and mechanical stress, 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.
atm relates to its own pressure and mechanical stress base unit by a factor of 101325. lb ft relates to its own torque (rotational force) base unit by a factor of 1.35582.
Conversion table
| Atmosphere (atm) | 101325 × pressure and mechanical stress base unit |
| Pound-foot (lb ft) | 1.35582 × torque (rotational force) base unit |

Frequently asked questions
Can Atmosphere be converted to Pound-foot?
Not directly. Atmosphere measures pressure and mechanical stress 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 Atmosphere used for?
The Atmosphere (atm) is a unit of pressure and mechanical stress. A standard atmosphere is exactly 101,325 pascals.
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 Atmosphere and Pound-foot don't, the tool flags them as not directly compatible rather than returning a meaningless number.
What should I convert Atmosphere to instead?
Use another pressure and mechanical stress unit, such as one of the related Atmosphere 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 Atmosphere (atm) and Pound-foot (lb ft) within the engineering converter.
A standard atmosphere is exactly 101,325 pascals. Torque from one pound-force at one foot.
Because Atmosphere measures pressure and mechanical stress 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.
