How to convert dynes per centimeter to millinewtons per meter
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 dyn/cm, b for the intermediate value in N/m, and y for the result in mN/m.
mN/m = dyn/cm × 0.001 ÷ 0.001
Worked examples
10 dyn/cm ≈ 10 mN/m
Step 1: (10 × 0.001) ≈ 0.01 N/m.
Step 2: 0.01 ÷ 0.001 ≈ 10 mN/m.20 dyn/cm ≈ 20 mN/m
Step 1: (20 × 0.001) ≈ 0.02 N/m.
Step 2: 0.02 ÷ 0.001 ≈ 20 mN/m.
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 Dynes per centimeter
Dynes per centimeter (dyn/cm) measures surface tension under the conventions above. The base value in N/m is (x × 0.001), where x is the numerical value in dyn/cm. Factors shown here are rounded for display; calculations use the stored factor.
About Millinewtons per meter
Millinewtons per meter (mN/m) measures surface tension under the conventions above. The base value in N/m is (x × 0.001), where x is the numerical value in mN/m. Factors shown here are rounded for display; calculations use the stored factor.
