MAGO-LIB

A Python library to format, parse, and convert numbers from meters to maghi.

What's this, though?

Meters (= boring 👎)

Since 2019, the metre has been defined as the length of the path travelled by light in vacuum during a time interval of 1/299792458 of a second, where the second is defined by a hyperfine transition frequency of caesium.

One second is the time that elapses during 9.192631770 x 10E9 cycles of the radiation produced by the transition between two levels of the cesium-133 atom.

What the hell is even that? How could you ever recreate a precise meter if you found yourself in a forest alone or shipwrecked on a desert island? Important questions. But the International System of Units doesn't care about you.

Maghi (= helpful! 👍)

How do you define a Mago? Simple enough! That's his height:

Of course, you'll have already figured the advantages of such unit of measurement:

• Simple and immediate definition
• The size of a Niccolò is UNIVERSALLY known on Planet Earth
• This Niccolò has always existed and forever will
• Its length is unchanged since the dawn of time and is extremely stable (contrary to a standard meter) to:
  • Thermal variations
  • Mechanical fatigue
  • Aging and degradation
  • Chemical stress
  • Verbal abuse
  • Intense math classes (up to 8 hours of continued exposure)
  • Electromagnetic radiation
  • Ionizing radiation (under testing)
• If you dip a meter in Nutella it'll be ruined, a Mago will smile and thank you
• Conversion between meters and maghi is very straightforward
• A handy Python library is available to help migrate the world from metric to magic

Conventions:

• We denote a mago with the character: ℳ
• One ℳ equals approximately 1.93 meters
• All the standard multiples and submultiples apply:

  Prefix	Name	Factor
  p	pico	1e-12
  n	nano	1e-9
  µ, u	micro	1e-6
  m	milli	1e-3
  c	centi	1e-2
  d	deci	1e-1
  		1e0
  da	deca	1e1
  h	etto	1e2
  k, K	kilo	1e3
  M	mega	1e6
  G	giga	1e9
  T	tera	1e12

Installation

Ensure you have Python and Pip installed in your system and run:

pip install magolib

Alternatively, you can clone this repository, cd into it, and run pip install .

Usage

First off, import magolib:

import magolib

Next, you can perform all these operations:

Convert meters to maghi

>>> magolib.meters_to_maghi(1.0)
0.5181347150259068
>>> magolib.meters_to_maghi(-0.58)
-0.3005181347150259
>>> magolib.meters_to_maghi(2.3e4)
11917.098445595855

Convert maghi to meters

>>> magolib.maghi_to_meters(1.0)
1.93
>>> magolib.maghi_to_meters(-42.5)
-82.02499999999999
>>> magolib.maghi_to_meters(1.9e-2)
0.03667

Format maghi as strings

>>> magolib.format_maghi(1.0)
'1.00 ℳ  (maghi)'
>>> magolib.format_maghi(3.4e-10)
'340.00 pℳ  (picomaghi)'
>>> magolib.format_maghi(23e6)
'23.00 Mℳ  (megamaghi)'

Convert maghi subunits

>>> magolib.convert_maghi(1.0, '', 'k')
0.001
>>> magolib.convert_maghi(5, 'h', '')
500.0
>>> magolib.convert_maghi(7.2, 'm', 'u')
7200.000000000001

Parse meters from string

>>> magolib.parse_meters('-2e3 km')
-2000000.0
>>> magolib.parse_meters('1 m')
1.0
>>> magolib.parse_meters('.3 dm')
0.03
>>> magolib.parse_meters('-2e3 km')
-2000000.0

Parse maghi from string

>>> magolib.parse_maghi('1ℳ')
1.0
>>> magolib.parse_maghi('1M')
1.0
>>> magolib.parse_maghi('3 mM')
0.003

Note: here for simplicity you can use an uppercase 'M' in place of the symbol 'ℳ'
