About the Torque Converter
Torque is turning force: force × distance from the pivot. One pound-foot is 1.35582 N·m. Wheel-nut and engine torque specs are usually given in N·m or lbf·ft.
The formula
Result = Value × (size of the “from” unit ÷ size of the “to” unit)

How to read your result
- Use the unit your torque wrench shows.
Worked example
Example: 110 pound-foot = 149.1399743 N·m
- Inputs: Value: 110; From: Pound-foot (lbf·ft); To: Newton-metre (N·m).
- Formula: Result = Value × (size of the “from” unit ÷ size of the “to” unit)
- Multiply by the number of N·m in one lbf·ft 110 × 1.355817948 = 149.1399743 N·m
- Result: 110 pound-foot = 149.1399743 N·m
- 1 lbf·ft = 1.355817948 N·m
- 1 N·m = 0.7375621493 lbf·ft
