Not the commenter, but I work in scientific software development and it's just a minefield of different units, so being explicit is generally very useful. Even if you can assume you can stick to metric (you can't), what different users want varies across countries. For e.g. here in the UK we often want to represent data as millilitres, but in France the same measurements are often centilitres. I don't use libraries to enforce it though, we did try this but found it quite clunky: https://pint.readthedocs.io/en/stable/ https://pint.readthedocs.io/en/stable/
