What are the 6 universal constants?
They include the velocity of light in vacuum (c); the charge of the electron, the absolute value of which is the fundamental unit of electric charge (e); the mass of the electron (me); Planck's constant (h); and the fine-structure constant, symbolized by the Greek letter alpha.
What is the value of HC in physics?
hc = 1.98644568×10-25 J.m.
What is constant number in physics?
The term "physical constant" refers to the physical quantity, and not to the numerical value within any given system of units.
