Physics constant, also called universal constant, are basic quantities observed in nature and the universe.  These physical constants are part of our everyday life and can be written in different units.  Physics constants are fixed numerical values that are used in physics equations and models to describe the behavior of the physical world.  These constants are fundamental to our understanding of physics and are based on experimental observations.  They are used in a wide range of physics calculations and equations, from quantum mechanics to classical mechanics, and are fundamental to our understanding of the physical world.
