So today I saw someone using that retard units and I get a little bit frustrated. Then a side project idea popped out; a website called something like retard units to non-retarded units. It would simply convert between units and have a clear message that suggests stop using any retard units. Then I hit google to check if similar website exists and boom! I found this:

https://tononretard.com/

ITS SO FUCKING BEAUTIFUL. Also it has a feature that blocks you from converting metric units to retard units. A wonderful masterpiece!
