I'm confused - the numbered ticks are micrometers apart, right? Should the symbol be with a lower case m? Or is it not a measurement in micrometers? I am unaccustomed to seeing the big M in this context.

I'm confused about the numbered ticks too. Why are they 11 micrometers apart? Does that mean each of the smaller ticks represents 1.1 micrometers? What kind of ruler is this? Altay8 (留言) 03:39, 7 October 2020 (UTC)[回覆]
