I mean the imperial system has it’s niche uses too. Fractional measurements are helpful if you’re doing multiple of something and you don’t want to calculate. What if you have 16 boards and you need to lay them out across 19 feet, what’s the width for each board and gap? Well its 19/16 or 1-3/16. And you could say your tolerance is ±1/16. Versus a decimal system, you need to hit 1.1875, with a ±0.0625 tolerance. Yeah no, imperial is better in that case.
Bur imperial does have it’s pains, especially once you start working with anything that isn’t a multiple of 2. Just wanted to point out it does have some uses.
Very concise answer. Linux was intimidating for me aswell when I first dual-booted it, and I didn’t understand it the first time around. But getting started in it was a lot of fun, and every time I came back, it got easier, until eventually it was the same for me as Windows
