Represent numerical values.
Constants are numerical values which are fixed but which may or may not be known. Variables are also numerical but may take a range of values. If a variable appears in an equation or inequality), it may be possible to solve the equation to ascertain the value of the variable.
In statistics numerical data is quantitative rather than qualitative.
Ratios ARE numerical.
A numerical expression uses numbers and operations. It also has an equal sign. An algebraic expression uses variables and operations. Unlike a numerical expression it does not have an equal sign.
Constant is a mathematical term that refers to a fixed value that does not change. In algebraic equations, constants are letters or symbols that represent specific numerical values. Constants can be added, subtracted, multiplied or divided in equations to generate different results.

The term that refers to the opposite of a constant is a variable. In mathematics, variables are symbols used to represent unknown or changing values, as opposed to constants which represent fixed values.
In statistics numerical data is quantitative rather than qualitative.
Physical constants are used for two main reasons. First, the quantitative predictions depend on the numerical values of the constants. An accurate knowledge of their values is therefore essential to achieve an accurate quantitative description of the physical universe. Second, the careful study of these constants can in turn test the overall consistency and correctness of the basic theories of physics themselves.

to store values
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.
A quantity that can have more than a single value is called a variable. In mathematics, variables represent unknown or changing values that can take on different numerical values.
