Tampilan
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.
Usage
Arguments
symbol
- If set to
yes
, the value is preceded by the symbol of the constant, followed by ≈ or = depending on whether or notround
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. If set to
auto
, the value is rounded so that the standard uncertainty is no more than 1.5 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 toonly
, only the reference is given. after
- Text (e.g. punctuation) to be shown after the constant before the reference.
