How to Convert Ounce-inches to Pound-inches
To convert ounce-inches to pound-inches, multiply the torque by the following conversion ratio: 0.0625 pound-inches/ounce-inch.
Since one ounce-inch is equal to 0.0625 pound-inches, you can use this simple formula to convert:
The torque in pound-inches is equal to the torque in ounce-inches multiplied by 0.0625.
For example, here's how to convert 5 ounce-inches to pound-inches using the formula above.

Ounce-inches and pound-inches are both units used to measure torque. Keep reading to learn more about each unit.
What Is an Ounce-inch?
An ounce-inch is a unit of torque equal to 0.0070616 newton-meters (N·m), the base unit for torque. 1/16 of a pound-inch (0.0070616 N·m). [1]
The ounce-inch is classified as a US customary and imperial unit of torque. Ounce-inches can be abbreviated as oz·in; for example, 1 ounce-inch can be written as 1 oz·in.
When working with ounce-inches (oz·in) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, ounce-inches (oz·in) are widely used across fine-tolerance laboratory, analytical, and micro-scale torque measurements 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 ounce-inches (oz·in) and pound-inches (lb·in), keep full floating-point precision (1 oz·in = 0.0625 lb·in; 1 lb·in = 16 oz·in) during intermediate calculations and round only the final pound-inch figure to match your instrument tolerance.
