SI Unit of Surface Tension is an important unit. The definition of surface tension states that it is a phenomenon which occurs when the surface of a liquid is in contact with another, liquid or non-liquid, surface. Liquids acquire the least surface area, hence, acting like an elastic sheet which creates surface tension.

## The SI unit of surface tension is N/m or Newton per Meter

The Surface Tension is calculated by the formula T=F/L where T is the surface tension of the liquid, F is force per unit length and L length of the acting force. The resulting T or the Surface Tension has the SI unit Newton per Meter, abbreviated as N/m. The cause of surface tension is the attraction of the particles on the surface towards the liquid.

Summary

## The SI unit of surface tension is?

The SI unit of Surface Tension is N/m. It is also called Newton per Meter. It is caused by the attraction of the particles, liquid or non-liquid, on the surface towards the liquid in contact with it.
