If we draw an imaginary line on the free surface of the liquid as shown in the below figure.

Then Surface tension of a liquid is measured by the force acting per unit length on either side of an imaginary line.

So  Surface tension of a liquid  is given by 

T= \frac{F}{l}

Where 

F\rightarrow force

l\rightarrow imaginary \: length

 So

[T]=\frac{[F]}{[l]}=\frac{[MLT^{-2}]}{L}=[MT^{-2}]
