Frequently asked questions
What units does this surface tension converter support?
It supports 8 units: Newton/meter (N/m), Millinewton/meter (mN/m), Dyne/centimeter (dyn/cm), Erg/centimeter² (erg/cm²), Gram-force/centimeter (gf/cm), Kilogram-force/meter (kgf/m), Pound-force/foot (lbf/ft), Pound-force/inch (lbf/in).
What is the base unit of surface tension?
The SI reference unit is the newton/meter (N/m). Every conversion is computed by converting the input to the base unit, then from the base unit to the target unit, so chained precision is preserved.
Is this converter accurate?
Yes. Conversion factors use exact legal definitions where they exist (for example 1 in = 25.4 mm exactly) and CODATA/ISO constants otherwise. Results are shown to up to 10 significant figures.
