When 1-2-3-4-5-6-7-8-9-10-11-12 doesn't make sense.

Most gauges I see measure by 1/8th inch but the only reason no finer divisions than that, is because they'd be too close together (or too thin) to read from a distance. That's not entirely true, I mean you can taper down the base of a gauge so spread out the measurement marks but most aren't that elaborate.

I got a rain gauge on Amazon that makes even less sense, measures 1/10ths of an inch, but I liked the design that can be read 20' away.

I like it...but it needs something to keep the birds off of it and from shitting in it.

1/10ths and 1/100ths are the standard way of measuring rainfall.

The Tru-Chek wedge is the gold standard for non weighing bucket rain gauges but they cost $30.

One side is graduated from 0.01” to 6” while the other side ranges from 0.1 mm to 150 mm. This 13” long gauge is constructed of heavy, weather-resistant plastic with permanently marked graduations.

Same problem. Needs a bird block.

I ordered a rain gauge off Amazon. It measures in 1/16ths inches. Not even Americans measure rain in 1/16ths.

Update: we got enough rain for me to notice: the gauge measures in 16ths for the first inch of rain and then in tenths for amounts greater than an inch.

Well, that's fun. Might as well throw in metric for the lulz. Not a separate set of graduations. Just start with fractional bullshit, go to decimal, then start the next inch at 50.8mm and go from there.

That thing in my case is a privacy fence it's mounted on. The birds have no desire to land on a slippery plastic rain gauge frame when there's wood fence posts all around it.

Now that what I'd linked has sat out in the sun for 2-1/2 years (minus winter months when I bring it indoors), the red plastic float to indicate water depth has faded to a nearly white color. I attempted to paint the edges of it with red nail polish but that wore away after one season of spring rain.

Otherwise the color of the acrylic body has remained stable, no significant yellowing and the depth markings haven't worn away but I am very gentle washing that area when I bring it indoors over the winter months.
