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 = require('hephys');
    var radiuscircle = 3.4 * HEP.cm; 
    var perimeter = radiuscircle * HEP.twopi;
    var area      = Math.pow( radiuscircle, 2) * HEP.pi;
    console.log( "area = %d cm2", area / HEP.cm2 );
    console.log( "area = %d m2", area / HEP.m2 );
    console.log( "perimeter = %d cm", perimeter / HEP.cm );
    console.log( "perimeter = %d m", perimeter / HEP.m );
