Variables change, constants do not.
Constants in the sense you mean are different to mathematical constants. They usually refer to a system in which two values are proportionate and so are of the units associated with the system.
No, not all do. The proportionality constants that change the units will have units themselves.
In mathematics, constants are fixed values that do not change. They can be located in various places, depending on the specific context. For example, in algebraic equations, constants are typically represented by specific letters or symbols and are found alongside variables. In geometric formulas, constants may be included as part of the formula itself. Constants can also be defined and used in mathematical functions, formulas, or mathematical theories.
Constants are those values which never change or are not changed during an experiment or calculation. Constants are numbers or letters that stand on their own this is stupid ("this is stupid" YOU KNOW WHAT EVERYTHING IN LIFE IS STUPID YOU OLD BITCH)
There are 4 constants.

there are three types of constants in COBOL 1. numeric literals 2. figurative constants 3. non-numeric literals
Symbolic constants are constants that the programmer has decided to give a symbolic name (usually one with a meaning to make it easy to remember) so he does not have to retype the numeric value every time he needs it and risk making an error. Many coding standards require ALL constants to be symbolic constants, even if only used once in the program.
Certain numbers like Pi and e and Euler's constant are know as math constants. A constant is a quantity assumed to have a fixed value in math. There are many constants, the ones I mentioned are only a few of the most famous ones.
Variables change, constants do not.
Integer constants Character constants Real/floating point constants String constants
Coding constants in c means writing the constants in a certain way that the c language understands.
It's arbitrary. That's the way that constants are defined.
The Universal Economic Constants are Production, Investment, Savings and Consumption.
