WTH Can't we change units without having to make a new sensor?

[charliesoap4]

A full 20% of my sensors are just templated versions of other sensors that I then had to hide. We can configure entities to show different names. Why can’t we configure entities to round values or to do minor calculations on them (convert units) without having to create an entire new entity?

Closing as a duplicate of:

Why do I need to create a new entity when I need to do a unit conversion? Why can't Lovelace handle this?

I have a handful of entities report in one unit of measurement, but I want to see them in another. For instance, I have a rain gauge that reports rainfall in mm, but I want to see it in inches. But to do this I need to make a whole new entity just to do the conversion? Why?!
