HEPhys Module
This module written in JavaScript has the units and constants used everyday in High Energy Physics calculations.
HEPhys is based on CLHEP - A Class Library for High Energy Physics, which is written in C++. This HEPhys specifically presents the same units and constants that are defined in files PhysicalUnits.h and PhysicalConstants.h.
One way to use it is:
var HEP = ; var radiuscircle = 34 * HEPcm; var perimeter = radiuscircle * HEPtwopi; var area = Math * HEPpi; console; console; console; console;
