Surface Tension Converter

Surface tension is a fascinating phenomenon that occurs at the interface of a liquid and a gas or another liquid. It is the result of cohesive forces among liquid molecules, causing the surface to behave like a stretched elastic membrane. This property gives rise to various interesting effects, such as capillary action, droplet formation, and the ability of certain insects to walk on water.

In scientific terms, surface tension is defined as the force acting parallel to the surface of a liquid, per unit length. It is commonly measured in units of force per unit length, such as newtons per meter (N/m) or dynes per centimeter (dyn/cm).

Let's explore the various surface tension units, along with their definitions and conversion factors.

  • Newton / meter (N/m): The force of one newton applied per meter length along the liquid surface. Newton per meter is the standard unit of surface tension.
    Conversion Factor: 1 N/m = 0.001 kN/m

  • Kilonewton / meter (kN/m): The force of one kilonewton applied per meter length along the liquid surface.
    Conversion Factor: 1 kN/m = 1000 N/m

  • Millinewton / meter (mN/m): The force of one millinewton applied per meter length along the liquid surface.
    Conversion Factor: 1 mN/m = 0.001 N/m

  • Gram-force / centimeter (gf/cm): The force of one gram-force applied per centimeter length along the liquid surface.
    Conversion Factor: 1 gf/cm = 0.980665 N/m

  • Dyne / centimeter (dyn/cm): The force of one dyne applied per centimeter length along the liquid surface.
    Conversion Factor: 1 dyn/cm = 0.001 N/m

  • Erg / centimeter² (erg/cm²): The work done against surface tension per square centimeter in ergs.
    Conversion Factor: 1 erg/cm² = 0.001 N/m

  • Erg / millimeter² (erg/mm²): The work done against surface tension per square millimeter in ergs.
    Conversion Factor: 1 erg/mm² = 0.1 erg/cm²

  • Poundal / inch (pdl/in): The force of one poundal applied per inch length along the liquid surface.
    Conversion Factor: 1 pdl/in = 5.4431 N/m

  • Poundal-force / inch (lbf/in): The force of one poundal-force applied per inch length along the liquid surface.
    Conversion Factor: 1 lbf/in = 175.1268 N/m
