How to Convert Pound-feet to Pound-inches
To convert pound-feet to pound-inches, multiply the torque by the following conversion ratio: 12 pound-inches/pound-foot.
Since one pound-foot is equal to 12 pound-inches, you can use this simple formula to convert:
The torque in pound-inches is equal to the torque in pound-feet multiplied by 12.
For example, here's how to convert 10 pound-feet to pound-inches using the formula above.
How Many Pound-inches Are in a Pound-foot?
There are 12 pound-inches in a pound-foot, which is why we use this value in the formula above.
Our pound-foot to pound-inch calculator automatically converts your torque measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Pound-feet and pound-inches are both units used to measure torque. Keep reading to learn more about each unit.
What Is a Pound-foot?
A pound-foot is a unit of torque equal to 1.3558179 newton-meters (N·m), the base unit for torque. Equal to 1.355818 N·m. [1]
The pound-foot is classified as a US customary and imperial unit of torque. Pound-feet can be abbreviated as lb·ft; for example, 1 pound-foot can be written as 1 lb·ft.
When working with pound-feet (lb·ft) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, pound-feet (lb·ft) are widely used across standard torque applications within US customary and imperial workflows, engineering documentation, and technical data sheets.
What Is a Pound-inch?
A pound-inch is a unit of torque equal to 0.1129848 newton-meters (N·m), the base unit for torque. 1/12 of a pound-foot (0.112985 N·m). [2]
The pound-inch is classified as a US customary and imperial unit of torque. Pound-inches can be abbreviated as lb·in; for example, 1 pound-inch can be written as 1 lb·in.
When working with pound-inches (lb·in) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, pound-inches (lb·in) are widely used across standard torque applications within US customary and imperial workflows, engineering documentation, and technical data sheets.
When converting torque between pound-feet (lb·ft) and pound-inches (lb·in), keep full floating-point precision (1 lb·ft = 12 lb·in; 1 lb·in = 0.0833333 lb·ft) during intermediate calculations and round only the final pound-inch figure to match your instrument tolerance.
