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 Newton-millimeter?
A newton-millimeter is a unit of torque equal to 1/1,000 of a newton-meter (0.001 N·m). Equal to 0.001 N·m. [2]
The newton-millimeter is classified as a metric and SI-compatible unit of torque. Newton-millimeters can be abbreviated as N·mm; for example, 1 newton-millimeter can be written as 1 N·mm.
When working with newton-millimeters (N·mm) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, newton-millimeters (N·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 newton-millimeters (N·mm), keep full floating-point precision (1 lb·ft = 1,355.8179483 N·mm; 1 N·mm = 0.000737562 lb·ft) during intermediate calculations and round only the final newton-millimeter figure to match your instrument tolerance.
