We symbolize the “dimensions” mass, length and time by M, L, T. We then write the dimensions of other physical quantities in terms of these. For example, velocity has dimensions

Using Dimensions
Some of the most interesting results of hydrodynamics, such as the sixteen-fold increase in flow down a pipe on doubling the radius, can actually be found without doing any calculations, just from dimensional considerations.
