Definition

A constant is a number that remains the same, unlike a variable, that can change.

Examples

$\displaystyle\pi$, or pi is a famous constant that is approximately 3.14159.

$\displaystyle e$, or e is another famous constant that is approximately 2.71828.

All numbers are constants because they do not change their value; they remain the same forever.
