What does this tool do?
Torque is a rotational force, and the units used depend on the workshop or the manual. This converter moves between newton-metres, pound-feet, pound-inches and kilogram-force metres.
The Formula
lb·ft = N·m ÷ 1.3558179; N·m = lb·ft × 1.3558179Frequently Asked Questions
Is lb-ft the same as ft-lb?
The physical quantity is the same, but lb-ft is the conventional order for torque. Use the manufacturer's stated unit and tighten to the specified figure.
How accurate is the conversion?
The factor is exact by definition, but torque wrenches have their own tolerance, often ±2–4%. Calibration matters more than the last decimal place.
