I'm afraid "you just do" is all there is to it. It's used for many things like density, Hammett equations and Resistivity. You need to give things labels so you don't end up writing "density" over and over and to help your equations look clean so they may be inspected properly.
Most variables and constants you will ever encounter in science will have a letter (of one alphabet or another) assigned to it...and guaranteed, they'll be sharing that letter with other numbers, also.
It's generally laid out so that you don't get two different properties using the same symbol in the same equation...but you're not always even that fortunate.
That said, most properties have more than one letter assigned, and many people use whatever they remember easiest when doing their own calculations that are not for others to understand. Using d for density is generally acceptable for small calculations such as calculating molarity.
