How to Convert Pound-inch to Newton-centimeter
- 1 lbf·in = 11.2984829 N·cm
- 1 N·cm = 0.08850745791 lbf·in
- Example: convert 15 lbf·in to N·cm: 15 lbf·in = 15 × 11.2984829 N·cm = 169.4772435 N·cm
Formula
N·cm = lbf·in × 11.29848290276
Derivation from SI units:
- 1 lbf·in = 4.4482216152605 N × 0.0254 m = 0.1129848290276 N·m
- 1 N·cm = 0.01 N·m
- 1 lbf·in = 0.1129848290276 N·m ÷ 0.01 N·m per N·cm = 11.29848290276 N·cm
Both units are defined exactly, so the factor is exact. Pound-inch definition: pound-inch; Newton-centimeter definition: newton-centimeter.
Worked examples
- A reading of 25 lbf·in converts to 282.4620726 N·cm.
25 lbf·in × 11.2984829 = 282.4620726 N·cm - A value of 75 lbf·in is 847.3862177 N·cm.
75 lbf·in × 11.2984829 = 847.3862177 N·cm
