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)
