Values of the fundamental physical constants, recommended for international use, are provided at this web site developed and maintained by the National Institute of Standards and Technology (NIST). These are the latest values of the constants recommended by CODATA (updated in 2006). Included are values for universal, electromagnetic, and atomic/nuclear constants, as well as non-SI units and conversion factors for energy equivalents. Users may also view background information related to constants, a searchable bibliography, and correlation coefficients between any pair of constants.

Values of the fundamental physical constants, recommended for international use, are provided at this web site. These are the latest values of the constants recommended by CODATA. Need background information? It's all there, in an easily-searchable format. Note: CODATA adjustment based on the recently revised SI is under review in 2018. By 12/31/2018, changes will be made that will significantly affect the uncertainties of many constants.
