gf·mm and pound-inches are both units used to measure torque. Keep reading to learn more about each unit.
What Is a Gram-force Millimeter?
A gram-force millimeter is a unit of torque equal to 0.000009807 newton-meters (N·m), the base unit for torque. Equal to 9.80665×10⁻⁶ N·m. [1]
The gram-force millimeter is classified as a metric and SI-compatible unit of torque. gf·mm can be abbreviated as gf·mm; for example, 1 gram-force millimeter can be written as 1 gf·mm.
When working with gf·mm (gf·mm) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, gf·mm (gf·mm) are widely used across fine-tolerance laboratory, analytical, and micro-scale torque measurements within SI metric 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 gf·mm (gf·mm) and pound-inches (lb·in), keep full floating-point precision (1 gf·mm = 0.000086796 lb·in; 1 lb·in = 11,521.246198 gf·mm) during intermediate calculations and round only the final pound-inch figure to match your instrument tolerance.
