About the Inch Pound to Newton Meter
The inch-pound to newton-metre converter changes torque values with the exact factor 1 in·lbf = 0.112985 N·m. Small torque settings for bicycles, electronics and firearms are often quoted in inch-pounds in the US and in newton-metres elsewhere, and using the wrong unit can strip threads or leave bolts loose.
How to use it
- 1Enter the amount in inch-pounds.
- 2The equivalent in newton-metres appears instantly.
- 3Press the ⇌ button to convert from newton-metres back to inch-pounds.
- 4Choose how many decimal places to show if you need more or less precision.
Worked example
150 in·lbf × 0.112985 ≈ 16.95 N·m, and 5 N·m ≈ 44.25 in·lbf.
How it works
Formula
N·m = in·lbf × 0.112984829
in·lbf = N·m × 8.850745
