*Here, we will find out the dimensional formula of Surface energy per unit area.* This term is related to surface tension. This surface energy relates to the surface of a liquid.

The formula of Surface energy per unit area = Surface energy /total area

The dimensional formula of energy = The dimensional formula of work = [ML^{2}T^{–2}] [see here how to find the dimensional formula of work ]

The dimension of area = [L^{2}]

**Hence, the Dimensional formula of Surface energy per unit area **

= **The dimensional formula of work / The dimensional formula of area ****= [ML ^{2}T^{–2}] **/

**[ L**

^{2}]=

**[ML**

^{0}T^{–2}] **Dimensional formula of Surface energy per unit area** **= [ML^{0}T^{–2}] **

Note: **Dimensional formula of Surface energy per unit area** = **Dimensional formula of Surface tension **
