Universe's constants now known with sufficient certainty to redefine the International System of Units

Fundamental constants are physical quantities that are universal in nature. For example, the speed of light in vacuum and the charge of a single electron are the same everywhere in the universe. That is why scientists would like to use invariant quantities of nature to define the seven base measurement units of the International System of Units (SI), or the modern metric system, rather than to rely on measurements of physical artifacts.
