CALCULATOR
Inch-lbs to Nm converter
Inch-lbs to Nm converter. Example: Value in lbf·in: 2.5 gives 0.282462072569 N·m. Converts torque units using pound-force, not pound mass. Standard gravity 9.80665 m/s², pound 0.45359237 kg and foot 0.3048 m define the factors. This is unit arithmetic, not a bolt tightening specification, structural recommendation or energy calculation.
How the calculation works
value × 1129848290276167/10000000000000000
Worked example
With value in lbf·in 1 lbf·in, result in n·m is 0.112984829 N·m.
