A physical constant is a physical quantity that is generally believed to be both universal in nature and constant in time. There are many physical constants in science, some of the most widely. — “Physical constant - Wikipedia, the free encyclopedia”, en.wikipedia.org

Some mathematical constants, such as e and π, arise in many different contexts. What it means for a constant to arise "naturally", and what makes a constant "interesting", is ultimately a matter of taste, and some mathematical constants are notable more for historical reasons than for. — “Mathematical constant - Wikipedia, the free encyclopedia”, en.wikipedia.org

The numerical values of a selected set of dimensional physical constants can be normalized to 1 if the units for time, length, mass, charge, and temperature are chosen appropriately. The resulting system of units would be one of several definitions of natural units. — “Dimensionless physical constant - Wikipedia, the free”, en.wikipedia.org
