A collection of unit of measure.

metrum

A collection of unit of measure.

metrum is a Python library that provides a simple and intuitive way to work with units of measurement in your code. It helps improve code readability and ensures consistency by converting all quantities to a standard set of reference units (SI units).

Installation

You can install metrum using pip:

pip install metrum

Usage

Using metrum is straightforward. Import the units you need and use them in your calculations.

from metrum.units import cm, g, usc_in

height = 180 * cm    # cm = 0.01 * m, so height is 1.8 (meters)
weight = 250 * g     # g = 0.001 * kg, so weight is 0.25 (kilograms)
width = 10 * usc_in  # usc_in = 0.0254 * m, so width is 0.254 (meters)

print(f"Height: {height} m")
print(f"Weight: {weight} kg")
print(f"Width: {width} m")

This makes your code more explicit and easier to understand, as the units are clearly stated. All conversions are handled automatically, bringing the values to the base SI units.

Reference Units

The library converts all units to a consistent set of reference units. The base units are the 7 SI base units, and the rest are SI derived units.

Quantity	Unit	Var. Name
Time	second	s
Length	metre	m
Mass	kilogram	kg
Electric current	ampere	A
Temperature	kelvin	K
Amount of substance	mole	mol
Luminous intensity	candela	cd
... and many more derived units ...

For each base unit, metrum also provides prefixed versions (pico, nano, micro, milli, centi, deci, deca, hetto, kilo, mega, giga, tera).

Special Units

Besides the SI units, metrum also supports a variety of special units, including:

• Time: min, h, d
• Length: au (astronomical unit), US Customary units (usc_in, usc_ft, usc_mi, etc.)
• Mass: t (tonne), Da (dalton), US Customary units (usc_oz, usc_lb, etc.)
• and many more.

For a complete list of all available units, see the metrum.units module documentation page.
