Which is quite low. My manual caliper is precise to the 1/10 of a mm, my electronic to 1/100 (but I would say 0,02 is the more realistic) The manual one is not good, harbor freight quality, electronic is a mituyo (not an entry level). Still - good ROI on both, got the electronic one because my eyesight is not that good anymore.

With a decent set of vernier calipers (I have Brown and Sharpe ones) they're accurate to 0.001" (0.02mm) every time. But what's nice about analog measuring tools is you can actually reliably achieve better accuracy--like 0.0005" +/- 0.00025"--by "reading between the lines". I can reliably take finishing cuts accurately to a few ten thousandths of an inch using vernier calipers (confirmed by checking with a micrometer accurate to 0.0001").

The only application I've encountered where digital tools work better for me is having a DRO on a mill is extremely convenient.

You really want to use a mike on this kind of precision. Calipers can be repeatable in a certain range but even then a readout from vernier gives too much error. Measuring a tenth of mm is acceptable (tho I'd never trust a vernier caliper measurement beyond 0.2). A hundredth IMO is wishful thinking.

I really cannot understand that you talk about micro meter (um) accuracy on a caliper. If you apply a tiny bit more pressure or it is under a tiny angle, the error is at least tens of um.

Interesting that you say that. My current backburner project is a display (TFT or PC) for Mitutoyo Digimatic. I can read the bright VFD display, but it struck me that others might find it difficult to read from across a workbench.

The proper term for calipers, for me, is Mitutoyo. I really want one of the solar models.

Why tho? The coin cell battery lasts years.
