How to convert newtons per meter to pounds-force per foot
Surface tension depends on the interface, composition, and temperature. Force per length and surface energy per area have equivalent dimensions, but use the physical interpretation appropriate to your experiment.
Use x for the value in N/m, b for the intermediate value in N/m, and y for the result in lbf/ft.
lbf/ft = N/m ÷ 14.593902937206362
Worked examples
10 N/m ≈ 0.685217658568 lbf/ft
Step 1: (10 × 1) ≈ 10 N/m.
Step 2: 10 ÷ 14.5939029372 ≈ 0.685217658568 lbf/ft.20 N/m ≈ 1.37043531714 lbf/ft
Step 1: (20 × 1) ≈ 20 N/m.
Step 2: 20 ÷ 14.5939029372 ≈ 1.37043531714 lbf/ft.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Newtons per meter
Newtons per meter (N/m) measures surface tension under the conventions above. The base value in N/m is (x × 1), where x is the numerical value in N/m. Factors shown here are rounded for display; calculations use the stored factor.
About Pounds-force per foot
Pounds-force per foot (lbf/ft) measures surface tension under the conventions above. The base value in N/m is (x × 14.5939029372), where x is the numerical value in lbf/ft. Factors shown here are rounded for display; calculations use the stored factor.
