New on CTAN: physconst
physconst is a package containing a collection of macros for commonly used physical constants, up-to-date as of CODATA 2018. Each constant is available in SI and cgs units, as well as eV, where appropriate.
This package is located at http://mirror.ctan.org/macros/latex/contrib/physconst More information is at https://www.ctan.org/pkg/physconst
Thanks for the upload. For the CTAN Team Manfred Lotz CTAN is run entirely by volunteers and supported by TeX user groups. Please join a user group or donate to one, see https://ctan.org/lugs .
physconst – Macros for commonly used physical constants
This package consists of several macros that are shorthand for a variety of physical constants, e.g. the speed of light. The package developed out of physics and astronomy classes that the author has taught and wanted to ensure that he had correct values for each constant and did not wish to retype them every time he uses them.
The constants can be used in two forms, the most accurate available values, or versions that are rounded to 3 significant digits for use in typical classroom settings, homework assignments, etc.
Most constants are taken from CODATA 2018, with the exception of the astronomical objects, whose values are taken from International Astronomical Union specified values. Constants that are derived from true constants, e.g. the fine structure constant, have been calculated using the accepted values of the fundamental constants.
