Ugh #1 Dislike seeing the unit (at all) next to the measurement
Logic: it already says the unit to the left, so don't repeat it next to measurements
Ugh #2 In the meantime, the unit is crammed, with no spacing, against the measurement. At least add a space between the two.
Ugh #3 You capitalized "in" to "IN". Therefore 0.1 IN looks like 0.11N (kills readability)
Ugh #4 Though I've chosen mm as my unit (and you display that on the left), you show CM next to each measurement. Pick one of the two and stick with it.
Ugh #5 You're showing 0 IN in a few measurements (while it's blank in other hours where there's 0 rainfall). Hey, if your program is able to produce a "0 IN", it's just as easy to recognize it's 0 and suppress display of it... go for blank instead of showing "0 IN".
Easiest fix: Stop adding the unit next to each measurement.
