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 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. [2]
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.
When converting torque between pound-feet (lb·ft) and gf·mm (gf·mm), keep full floating-point precision (1 lb·ft = 138,254.954376 gf·mm; 1 gf·mm = 0.000007233 lb·ft) during intermediate calculations and round only the final gram-force millimeter figure to match your instrument tolerance.
