<r3d:remarks>CODATA Internationally recommended 2010 values of the Fundamental Physical Constants
|
|
https://www.nist.gov/pml/data/physicalconst.cfm
|
|
This site addresses three topics: fundamental physical constants, the International System of Units (SI), which is the modern metric system, and expressing the uncertainty of measurement results. Both essential information and background information are given for each topic.</r3d:remarks>
