Convert tightening torque between newton-metres (Nm), pound-feet (lb-ft) and kilogram-metres (kg-m). Type a value in any unit to see the others, with a quick reference table for common figures.
Torque Converter — Nm · lb-ft · kg-m
| Nm | lb-ft | kg-m |

1 Nm = 0.737562 lb-ft = 0.101972 kg-m. Always tighten to the figure and sequence in your manual; many fasteners (head bolts, hubs) also need an angle (torque-to-yaw) stage that a converter can't replace.
Getting torque right
1 Nm = 0.7376 lb-ft = 0.1020 kg-m. Always tighten to the value and the sequence in your vehicle’s manual. Many critical fasteners — cylinder-head bolts, driveshaft/hub nuts, some suspension bolts — use a “torque-to-yaw” method: an initial Nm figure followed by a set number of degrees. A converter handles the units, but it can’t replace the angle stage or a calibrated torque wrench.
Frequently asked questions
What is 100 Nm in lb-ft?
100 Nm is about 73.8 lb-ft (10.2 kg-m).
What torque for wheel/lug nuts?
Most cars are around 110–120 Nm (≈81–89 lb-ft), but check your manual — alloy and steel wheels and different stud sizes vary. Re-check after ~50 km on new fitments.
Is kg-m the same as kgf·m?
Yes — kg-m here means kilogram-force metre (kgf·m), the older unit still printed in some manuals.
