List of physical constants. The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured.
12 Οκτ 2018 · Meet the Constants. The revised SI rests on a foundation of seven values, known as the constants. (SI is the acronym for the International System of Units, which is informally known as the metric system.) The values of the constants are the same everywhere in the universe.
A list of physical constants that you will need to finish some of the computation problems in this book.

There are many physical constants in science, some of the most widely recognized being the speed of light in vacuum c, the gravitational constant G, the Planck constant h, the electric constant ε0, and the elementary charge e.
Physical constant, any of a set of fundamental invariant quantities observed in nature and appearing in the basic theoretical equations of physics. Accurate evaluation of these constants is essential in order to check the correctness of the theories and to allow useful applications to be made on.
