Magnitude Order

magorder

This library streamlines the conversion between different orders of magnitude, like transforming nm (nanometers) to meters, or kilobytes to gigabytes.

It is meant to provide a drop-in mechanism that is simple and consistent to manipulate such conversions.

Installation

Install it as usual:

pip install magorder

Dependencies

This library has no runtime dependencies.

Usage

To use the library:

# import the MagnitudeUnit class that meets your requirements
from magorder.stdsi import StdSIMagnitudeUnit

# create a magorder object, associated with an unit
mag = StdSIMagnitudeUnit("m")

# transform can convert from a different order of magnitude to the base unit
assert mag.transform(0.1, "km") == 100
assert mag.transform(100_000_000, "µm") == 100
assert mag.transform(100_000_000_000_000_000_000_000_000.0, "ym") == 100
assert mag.transform(0.0000000000000000000001, "Ym", decimals=3) == 100

Or to transform data units:

from magorder.data import SIDataMagnitudeUnit, IECDataMagnitudeUnit

mags = SIDataMagnitudeUnit("b")
assert mags.transform(1, "kb") == 1000
assert mags.transform(1, from_unit="Gb", to_unit="kb") == 1_000_000

mags = IECDataMagnitudeUnit("b")
assert mags.transform(1, "Kib") == 1024
assert mags.transform(4096, from_unit="Mib", to_unit="Gib") == 4

See the module tests for more examples.
