Yeah, that why IEC units carry only one meansing. It's all that stupid JEDEC that standardized SI units to binary multiples. Dumbest shit I've ever seen.
I'm using it for a year and it came a long way. Though still in beta and still have some major bummers (which require hacking). But it only came out in 2023. The next update should add a ton of QoL things, so this will be pretty exciting.
Since for me it has all the needed features, for me β it's by far superior (even compared to LuaLaTeX which is the last thing I used). But some people, mainly from academia, are still can't switch due to some features missing. A few people were able to create thesis in Typst (including myself). In the long run it will be 100% superior. In the mean time, there are a few hacks to enable some features that are otherwise not implemented yet.
The last point: I use MuPDF + entr as zarhura crush as a mf, not usable at all. Some others use typst-preview which can be used in the browser and as a VS Code extension. But I use Neovim btw and the web version lack a few key features. Anyway, I use mupdf+entr+nvim for many months now and it's more than enough for me.
The web version, for me, is just to share my local project with someone, that's it.
I would recommend pdm and micromamba.
