SI Unit of Surface Tension is

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.
