# CODATA recommended values of the fundamental physical constants: 2018

@article{Mohr2021CODATARV, title={CODATA recommended values of the fundamental physical constants: 2018}, author={Peter J. Mohr and Barry N. Taylor and David B. Newell}, journal={Reviews of Modern Physics}, year={2021} }

This paper gives the 2010 self-consistent set of values of the basic constants and conversion factors of physics and chemistry recommended by the Committee on Data for Science and Technology (CODATA) for international use. The 2010 adjustment takes into account the data considered in the 2006 adjustment as well as the data that became available from 1 January 2007, after the closing date of that adjustment, until 31 December 2010, the closing date of the new adjustment. Further, it describes in…
