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). [1]
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.
What Is a Kilogram-force Millimeter?
A kilogram-force millimeter is a unit of torque equal to 0.0098067 newton-meters (N·m), the base unit for torque. Equal to 0.00980665 N·m. [2]
The kilogram-force millimeter is classified as a metric and SI-compatible unit of torque. kgf·mm can be abbreviated as kgf·mm; for example, 1 kilogram-force millimeter can be written as 1 kgf·mm.
In the metric system, "kilo" is the standard SI prefix for thousands, or 10³. This makes the kilogram-force millimeter (kgf·mm) a convenient decimal multiple of the newton-meter (N·m).
In practice, kgf·mm (kgf·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-inches (lb·in) and kgf·mm (kgf·mm), keep full floating-point precision (1 lb·in = 11.5212462 kgf·mm; 1 kgf·mm = 0.0867962 lb·in) during intermediate calculations and round only the final kilogram-force millimeter figure to match your instrument tolerance.
