Newton-metres to Pound-inches Converter N·m → lbf·in
1 newton-metre (N·m) = 8.850745791 pound-inches (lbf·in). Type a value below — the conversion happens instantly, entirely on your device.
1 N·m = 8.850745791 lbf·in
5 newton-metres = 44.253729 pound-inches
5 × 8.85075 = 44.253729
1 N·m equals 8.85075 lbf·in, so multiplying by 8.85075 converts the value. The result describes the exact same quantity — only the measuring stick changes.
How to convert newton-metres to pound-inches
pound-inches = newton-metres × 8.850745791 — multiply the newton-metre value by 8.85075.
Example: 5 N·m = 44.2537 lbf·in.
To convert the other way: newton-metres = pound-inches ÷ 8.850745791
Newton-metres to pound-inches multiplies by about 8.851: a 5 N·m spec is about 44.3 lbf·in. Common for electronics, bicycle and precision assembly work where torque is small.

About the units
What is a newton-metre?
The SI unit of torque — one newton of force at one metre from the axis. Engine and fastener torque is specified in N·m across most of the world.
What is a pound-inch?
A pound-inch is one-twelfth of a pound-foot (about 0.113 N·m) — used for small fasteners and precision assemblies.
Frequently asked questions
How many pound-inches are in 1 newton-metre?
