Dimensional Formulas

All physical quantities can be expressed in terms of seven fundamental (base) quantities such as mass, length, time, temperature, electric current, luminous intensity, and amount of substance. These seven quantities are called the seven dimensions of the physical world.

The dimensional formula is a compound expression showing how and which of the fundamental quantities are involved in making that physical quantity.

We can use symbols instead of the names of the base quantities. M, L, and T are used to represent the dimensions of the three mechanical quantities mass, length, and time respectively.
