This template allows the values of physical constants to be quickly entered in articles. As of now, it returns CODATA 2010 recommended values, but using the template allows all the articles using it to be updated at once when more recent values become available. In particular, if the proposed new SI definitions are approved, the numerical values of the constants used in the new definitions will become exact whereas those of the constants used in the old definition will acquire an uncertainty.

Arguments

symbol
If set to yes, the value is preceded by the symbol of the constant, followed by or = depending on whether or not round is set.
round
If omitted, the value is shown along with its standard uncertainty. If set to an integer n, the value is rounded to the first n digits after the decimal point (retaining trailing zeros). If set to auto, the value is rounded to the most digits such that the standard uncertainty is no more than 0.5 units in the last place.
unit
If set to no, the unit of measurement is not shown.
ref
If set to no, no reference is given. If set to only, only the reference is given.
after
Text (e.g. punctuation) to be shown after the constant before the reference.
runc
If set to yes, this will provide only the relative standard uncertainty of the value and its reference.
