This template provides easy inclusion of the latest CODATA recommended values of physical constants in articles. It gives the most recent values published, and will be updated when newer values become available, which is typically every four years.

The values have been updated to the CODATA 2022 values. This includes the 2019 revision of the SI, which made the values of several constants exact (e.g. e), whereas some previously exactly defined constants acquired an uncertainty (e.g. μ0).

Usage

[edit]

Arguments

[edit]
symbol
If set to yes, the value is preceded by the symbol of the constant, followed by ≈ or = depending on whether 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.
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.
