Newton meter

Definition: A newton meter (symbol: N·m) is the SI unit of torque, or moment of force. One newton meter is the turning effect of a force of one newton applied at the end of a one-meter lever arm, perpendicular to it.
History / origin: It is a derived SI unit combining the newton - the unit of force named after Sir Isaac Newton - with the meter. A newton meter is dimensionally the same as the joule, but the joule is reserved for energy while torque is expressed in newton meters.
Current use: The newton meter is the standard torque unit worldwide for engineering, physics and modern vehicle specifications, where fastener, axle and engine torques are quoted in N·m.

Pound-force inch

Definition: A pound-force inch (symbol: lbf·in), often written lb-in or in-lb, is a unit of torque equal to one pound-force applied on a one-inch lever arm. There are exactly 12 pound-inches in one pound-foot.
History / origin: Like the pound-foot it derives from the pound-force and the inch, one twelfth of a foot. It is the small-scale companion to the pound-foot, suited to light fasteners where a pound-foot would be an awkwardly small fraction.
Current use: Pound-inches are widely used for low-torque assembly in the United States - electronics, instruments, small engines and bicycle parts - and are marked on inch-pound torque wrenches and torque screwdrivers.

How to convert newton meters to pound-force inches

To convert newton meters to pound-inches, multiply the newton-meter value by 8.850745454. For example, 5 N·m = 5 × 8.850745454 = 44.25 lbf·in.

One pound-inch is 0.1129848333 newton meters, so to go from newton meters to pound-inches you divide by 0.1129848333 - equivalently, multiply by 8.850745454:

lbf·in = N·m ÷ 0.1129848333 = N·m × 8.850745454
1 N·m = 8.850745454 lbf·in · 1 lbf·in = 0.1129848333 N·m

Example. To convert 3 N·m to pound-inches, multiply by 8.850745454: 3 N·m = 3 × 8.850745454 = 26.55 lbf·in. Going the other way, 50 lbf·in is 50 × 0.1129848333 = 5.65 N·m.

When you need to convert newton meters to pound-force inches

Newton-meter to pound-inch conversion is handy for small fasteners where torque is specified in inch-pounds. Common cases:

Setting an inch-pound (in-lb) torque screwdriver from a metric N·m specification.
Assembling electronics, optics and instruments whose torque specs are given in pound-inches.
Following US small-engine and bicycle specs in lb-in when your gauge reads N·m.
Converting low torque values that would be awkward fractions of a pound-foot.
Checking delicate-fastener torque against an imperial in-lb table.

Frequently asked questions

How do I convert newton meters to pound-inches?
