For example code related to jumpdrive digiline control such conversion is somewhat offtopic, and should be moved to another more touchscreen-focused page. But @[[User:BuckarooBanzai]], was the original layout of the UI significant / does preserving it matter?

<User:SwissalpS> Some more comments explaining what the convert function is about and why it is needed, would make understanding the formulas like "v*2*15/13*0.35" better.

<User:Huhhila> That particular formula is taken from https://minetest.gitlab.io/minetest/formspec/#migrating-to-real-coordinates and results in the following:
