Enter the force and the length into the calculator to determine the surface tension.

## Surface Tension Formula

The following formula is used to calculate a surface tension.

*γ* = 1/2 * F / L

- Where
*γ*is the surface tension (N/m) - F is the force (N)
- L is the length (m)

## Surface Tension Definition

Surface tension is defined as the force exerted on the surface of an object within a liquid.

## Surface Tension Example

How to calculate surface tension?

**First, determine the force acting on the object.**For this example the force is found to be 45 N.

**Next, determine the length.**The length the force is acting on is found to be 10 m.

**Finally, calculate the surface tension.**Using the formula we find the surface tension to be 1/2*45/10 = 2.25 N/m.

## FAQ

**What is surface tension?**

Surface tension is a force exerted on the surface of an object that is placed on top of a liquid. The force is caused by the tendency of the liquid to have the shape with the least surface area.
