rain / precipitation on graph shown as mm

[two-dogs]

rain forecast in mm's
all other measures are in US, with measurable/s set to US
can rain have option for inches?

i would not know a mm of rain if i was under it :)

I did actually try to implement this - but it turned out to be an absolute pain.

There isn't enough space on the graph to display small amounts of rainfall - for example 0.1mm of rain is 0.004 inches but there might be enough space to display it as a fraction - something like:
1
/
250

But to do that I need some kind of library to calculate fractions...

A bad idea, but https://github.com/Qalculate/libqalculate can do this.

Another idea: "0.004 in" show as "4 mil"
