finesse.utilities.units module

Convenience objects and functions for unit manipulation.

class finesse.utilities.units.SI(*values)[source]

Bases: Enum

Enum defining common SI unit constant names. Look-up the corresponding values with the finesse.utilities.SI_MAP dictionary.

Examples

To get the constant for SI.MILLI simply look-up:

>>> SI_MAP[SI.MILLI]
1e-3

ATTO = 2

CENTI = 8

DECI = 9

FEMTO = 3

GIGA = 13

KILO = 11

MEGA = 12

MICRO = 6

MILLI = 7

NANO = 5

NONE = 10

PETA = 15

PICO = 4

TERA = 14

YOCTO = 0

ZEPTO = 1

finesse.utilities.units.get_SI_value(name)[source]

Get an SI value by name.

Valid names correspond to the values() of the finesse.utilities.SI_LABEL dict.

Parameters

namestr: Label name of the SI value (e.g. “m” for milli, “G” for giga).

Returns

valuefloat: Value corresponding to the SI name.
