Units

Base and auxiliary units and constants used througout the library

This help keep track of the units we are usings and makes it easier to interact with other libraries or with the user (read in and display).

Usage example:

>>> from bctools.util import units as u
>>> energy = 500 * u.keV
>>> print("{} MeV".format(energy/u.MeV))
0.5 MeV

bctools.util.units.GeV = 1000000.0

bctools.util.units.MeV = 1000.0

bctools.util.units.TeV = 1000000000.0

bctools.util.units.cm = 1

Base distance unit

bctools.util.units.cm2 = 1

bctools.util.units.deg = 0.017453292519943295

bctools.util.units.eV = 0.001

bctools.util.units.erg = 624150907.45

bctools.util.units.halfpi = 1.5707963267948966

bctools.util.units.inf = inf

bctools.util.units.keV = 1

Base energy units

bctools.util.units.m = 100

bctools.util.units.meter = 100

bctools.util.units.pi = 3.141592653589793

bctools.util.units.rad = 1
