Reviewed 2010 by P.J. Mohr (NIST). Mainly from the “CODATA Recommended Values of the Fundamental Physical Constants:
2006” by P.J. Mohr, B.N. Taylor, and D.B. Newell in Rev. Mod. Phys.

(2008) 633. The last group of constants (beginning with the Fermi
coupling constant) comes from the Particle Data Group. The figures in parentheses after the values give the 1-standard-deviation uncertainties
in the last digits; the corresponding fractional uncertainties in parts per 10

(ppb) are given in the last column. This set of constants (aside
from the last group) is recommended for international use by CODATA (the Committee on Data for Science and Technology). The full 2006
CODATA set of constants may be found at
