How to Convert Pound-force Feet to Pound-force Inches
To convert pound-force feet to pound-force inches, multiply the moment of force by the following conversion ratio: 12 pound-force inches/pound-force foot.
Since one pound-force foot is equal to 12 pound-force inches, you can use this simple formula to convert:
The moment of force in pound-force inches is equal to the moment of force in pound-force feet multiplied by 12.
For example, here's how to convert 5 pound-force feet to pound-force inches using the formula above.
How Many Pound-force Inches Are in a Pound-force Foot?
There are 12 pound-force inches in a pound-force foot, which is why we use this value in the formula above.
Our pound-force foot to pound-force inch calculator automatically converts your moment of force measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Pound-force Feet and pound-force inches are both units used to measure moment of force. Keep reading to learn more about each unit.
What Is a Pound-force Foot?
A pound-force foot is a unit of moment of force equal to 1.3558179 newton meters (N·m), the base unit for moment of force. Equal to 1.35582 N·m. [1]
The pound-force foot is classified as a US customary unit of moment of force. Pound-force Feet can be abbreviated as lbf·ft; for example, 1 pound-force foot can be written as 1 lbf·ft.
When working with pound-force feet (lbf·ft) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, pound-force feet (lbf·ft) are widely used across standard moment of force applications within US customary workflows, engineering documentation, and technical data sheets.
What Is a Pound-force Inch?
A pound-force inch is a unit of moment of force equal to 0.1129848 newton meters (N·m), the base unit for moment of force. Equal to 0.112985 N·m. [2]
The pound-force inch is classified as a US customary unit of moment of force. Pound-force Inches can be abbreviated as lbf·in; for example, 1 pound-force inch can be written as 1 lbf·in.
When working with pound-force inches (lbf·in) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, pound-force inches (lbf·in) are widely used across standard moment of force applications within US customary workflows, engineering documentation, and technical data sheets.
When converting moment of force between pound-force feet (lbf·ft) and pound-force inches (lbf·in), keep full floating-point precision (1 lbf·ft = 12 lbf·in; 1 lbf·in = 0.0833333 lbf·ft) during intermediate calculations and round only the final pound-force inch figure to match your instrument tolerance.
