Susan, I would say round to the nearest mm for the records that have
decimal values from inches conversion; your thoughts?

I don't need you to handle it, but you're probably the one who's going
to handle it anyway.  "It" being the question of the fractional
millimeters of rain measurement that are currently present in the data.
(There's 2 decimal points of precision (1/100th of a mm!) in the data
Tabby sent.) See the thread:

Or we just do something like round the data to the nearest even mm.
