How to Convert Pound-foot to Newton-centimeter
- 1 lbf·ft = 135.5817948 N·cm
- 1 N·cm = 0.007375621493 lbf·ft
- Example: convert 15 lbf·ft to N·cm: 15 lbf·ft = 15 × 135.5817948 N·cm = 2033.726922 N·cm
Formula
N·cm = lbf·ft × 135.5817948331
Derivation from SI units:
- 1 lbf·ft = 4.4482216152605 N × 0.3048 m = 1.3558179483314 N·m
- 1 N·cm = 0.01 N·m
- 1 lbf·ft = 1.355817948331 N·m ÷ 0.01 N·m per N·cm = 135.5817948331 N·cm
Both units are defined exactly, so the factor is exact. Pound-foot definition: pound-foot; Newton-centimeter definition: newton-centimeter.
Worked examples
- A reading of 30 lbf·ft converts to 4067.453845 N·cm.
30 lbf·ft × 135.5817948 = 4067.453845 N·cm - A value of 200 lbf·ft is 27116.35897 N·cm.
200 lbf·ft × 135.5817948 = 27116.35897 N·cm

Where it's used
Pound-feet are used for US car wheel-lug and bolt torques, while newton-centimeters appear in dental and medical implant torque (e.g. 35 N·cm). Both measure torque (moment of force), so the conversion is a fixed factor.
