Convert inch-pounds to newton metres— the formula
Inch-pounds convert to newton metres by multiplying by the published conversion factor. The factor below is exact to the precision shown, sourced from the citation under the formula.
Newton metre: SI coherent derived unit (BIPM). 1 lbf = 4.4482216152605 N; 1 ft = 0.3048 m, so 1 ft·lbf = 1.3558179483314004 N·m; 1 in·lbf = 1/12 ft·lbf. 1 kgf = 9.80665 N exactly, so 1 kgf·m = 9.80665 N·m (NIST SP 811).
