Whereas the physical quantity indicated by a physical constant does not depend on the unit system used to express the quantity, the numerical values of dimensional physical constants do depend on choice of unit system. The term "physical constant" refers to the physical quantity, and not to the numerical value within any given system of units. For example, the speed of light is defined as having the numerical value of 299792458 when expressed in the SI unit metres per second, and a… Webb12 jan. 2024 · Physics Fundamental Constants The Organic Chemistry Tutor 5.84M subscribers 8.6K views 4 weeks ago This physics video tutorial provides a basic introduction into the …
