SUMMARY
Strain is a dimensionless quantity, defined as the change in length per unit length. It does not possess any units, confirming its unitless nature. The discussion emphasizes the importance of dimensional analysis in understanding this concept, reinforcing that strain is fundamentally expressed in terms of length without any reference to mass or time.
