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.
The Greek letter "rho" (ρ) is commonly used to represent density in physics and engineering equations because it is a standard symbol used to denote mass per unit volume. Using a consistent symbol helps to avoid confusion and maintain clarity in scientific communication.

What the symbol for density?
The symbol for density is represented by the Greek letter rho (ρ).
What is the Greek character for density?
The Greek character for density is "ρ" and it is pronounced as "rho".
What is the density of plexiglas?
The density of plexiglas typically ranges from 1.17 to 1.20 grams per cubic centimeter.
Symbol for density?
In lower classes viz sixth standard, the first letter of the word "density" ie 'd' is used. But later in higher studies instead 'd', 'rho' the greek letter is used as the symbol for density.
Meaning of p in the symbol for density?
The symbol for density, "ρ", is the Greek letter rho. It represents the density of a substance, which is defined as mass per unit volume. It is commonly used in physics and chemistry to quantify how much mass is contained in a specific volume of a material.
How is density related to water?
The density of water is rho = 1,000 kg/m³ or rho = 1 g/cm³ at the temperature of 3.98 degrees Celsius. Density rho = mass / Volume.
What the symbol for density?
The symbol for density is represented by the Greek letter rho (ρ).
What is the value of density of glasses?
The density of glass is about rho = 2,500 kg/m³ or rho = 2,5 g/cm3.
Density of anitmony?
The density of the metal antimony is rho = 6,680 kg/m³ or rho = 6.68 g/cm³.
What is The density of alumimun?
The density of the metal alumium is rho = 2,710 kg/m³ or rho = 2.71 g/cm3.
What is the Greek character for density?
The Greek character for density is "ρ" and it is pronounced as "rho".
What is the mathematical symbol for density?
Density is the lower case greek letter rho.
What is the density of plexiglas?
The density of plexiglas typically ranges from 1.17 to 1.20 grams per cubic centimeter.
What is the density of the unknown liquid rho unknown?
1.51
Density of chromium?
The density of chromium is approximately 7.19 grams per cubic centimeter at room temperature.
What is the mass of a metal that has a density of 15g cm3 and a volume of 10 cm3?
m = mass rho = density V = volume rho = m/V m = rho * V = (15 g/cm^3) * (10 cm^3) = 150 g
What is the density of tin in grams divided by milliliters?
The density of tin is approximately 7.3 grams per milliliter.
