conversions.prefix_conversions¶

Convert International System of Units (SI) and Binary prefixes

Classes¶

`BinaryUnit`	Create a collection of name/value pairs.
`SIUnit`	Create a collection of name/value pairs.

Functions¶

`convert_binary_prefix`(→ float)	Wikipedia reference: https://en.wikipedia.org/wiki/Metric_prefix
`convert_si_prefix`(→ float)	Wikipedia reference: https://en.wikipedia.org/wiki/Binary_prefix

Module Contents¶

class conversions.prefix_conversions.BinaryUnit(*args, **kwds)¶

Bases: enum.Enum

Create a collection of name/value pairs.

Example enumeration:

>>> class Color(Enum):
...     RED = 1
...     BLUE = 2
...     GREEN = 3

Access them by:

attribute access:
```
>>> Color.RED
<Color.RED: 1>
```
value lookup:
```
>>> Color(1)
<Color.RED: 1>
```
name lookup:
```
>>> Color['RED']
<Color.RED: 1>
```

Enumerations can be iterated over, and know how many members they have:

>>> len(Color)
3

>>> list(Color)
[<Color.RED: 1>, <Color.BLUE: 2>, <Color.GREEN: 3>]

Methods can be added to enumerations, and members can have their own attributes – see the documentation for details.
