sry last time I said divided by stress. its actually multiplied but none the less strain has no dimension so stess is force per unit area ,ans is this sorry if u didnt understand my explanation
Explanation:
pressure = force / area
stress. = (force / area)x strain
strain has no dimension as it is ratio of lengths
so dimensionally these are the same
strain = change in length / total lengta
