Pound-feet and kgf·mm 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 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-feet (lb·ft) and kgf·mm (kgf·mm), keep full floating-point precision (1 lb·ft = 138.2549544 kgf·mm; 1 kgf·mm = 0.007233 lb·ft) during intermediate calculations and round only the final kilogram-force millimeter figure to match your instrument tolerance.
