Pound-inch (lbf·in)
The pound-inch (lbf·in, written in-lb on many tools) is one twelfth of a pound-foot, about 0.113 N·m.
Symbol: lbf·in (ASCII: lbf-in)
Quantity: torque (moment of force)
SI relation: 1 lbf·in = 0.1129848290276 N·m (exact)
Derivation: 1 lbf·in = 4.4482216152605 N × 0.0254 m = 0.1129848290276 N·m
Exact: yes, by definition
Typical uses
- Small fastener and electrical-terminal torques
- Bicycle and firearm assembly specs
- Torque screwdrivers
