The science-constants package


This package provides constants and conversion factors commonly used in mathematics and physical sciences. The motivation is to make it easier to use ghci for quick scientific calculations [without the need to search for the constant values over the internet.] To make it even friendlier, if multiple conventional names of a constant exist, they all are provided by this package. Wherever possible, TeX-style named constants are also provided.

This package utilizes untyped values (i.e. untyped in terms of unittyped, dimensional, and similar libraries); and unless otherwise specified, the constants are in SI units: mass in kilograms, length in meters, etc.

Due to floating-point calculation errors and to improve accuracy, the package internally uses exact values even in cases where constants can be mathematically derived one from another.

Most of the constants values were taken from the Fundamental Constants Data Center of the NIST Physical Measurement Laboratory (by Barry N. Taylor of the Data Center in close collaboration with Peter J. Mohr of the Physical Measurement Laboratory's Atomic Physics Division.)
