Surface Tension is the elastic tendency of a fluid surface which makes it acquire the least surface area possible; in other words, it is the force that causes the surface of a liquid to be form a layer. Surface tension allows insects, usually denser than water, to float and stride on a water surface. The SI unit for surface tension is newton per meter (N/m). This Surface Tension converter allows you to convert dyne/centimeter (dyn/cm), erg/sq. centimeter (erg/cm²), erg/sq. millimeter (erg/mm²), gram-force/centimeter (gf/cm), millinewnon/meter (mN/m), newton/meter (N/m), poundal/inch (pdl/in), pound-force/inch (lbf/in), among other units related to Surface Tension.
