Units

This module provides basic support for calculations with units.

class xconf.misc.units.Angle(magnitude, dimension)

Define an angle with unit. Allowed units are ‘mdeg’, ‘deg’, ‘urad’, ‘mrad’ and ‘rad’.

class xconf.misc.units.Energy(magnitude, dimension)

Define an energy with unit. Allowed units are ‘meV’, ‘eV’, ‘KeV’, ‘MeV’, ‘GeV’, ‘mJ’, ‘J’, ‘KJ’, ‘MJ’ and ‘GJ’.

class xconf.misc.units.Length(magnitude, dimension)

Define a length with unit. Allowed units are ‘pm’, ‘angstrom’, ‘nm’, ‘um’, ‘mm’, ‘m’ and ‘km’.

class xconf.misc.units.Quantity(magnitude, dimension)

Quantity base class. A quantity is made up of magnitude and dimension.

compare(other, op)

Common method to check on the nature of operands.

convert(new_dimension)

Convert this quantity to a another dimension new_dimension (e.g. to do a common mathematical operation on them). Will raise an error if the new dimension is not allowd.

free()

Drop all unit support and just return the quantities magnitude.

operate(other, op)

Common method to check on the nature of operands.

class xconf.misc.units.SolidAngle(magnitude, dimension)

Define an solid angle with unit. Allowed units are ‘sr’ and ‘msr’.
