WebA dimensionless quantity (also known as a bare quantity, pure quantity as well as quantity of dimension one) is a quantity to which no physical dimension is assigned, … WebApr 7, 2024 · As these quantities are often a pure ratio between similar physical quantities they do not possess dimension and hence no units. But when we look at the dimensionless quantity- angle, it has a unit assigned to it, the radians or degrees. So we cannot say that all dimensionless quantities are unit-less. Thus the correct answer is option C. Note ...
