Like l.c for metre rule is 0.5mm but for 1 MEASUREMENT we take 1mm...so I was asking if we do the same for caliper
Metre rule has uncertainty of 0.5mm but the fact that we take two readings it then becomes 1mm and for Vernier calliper we take one reading so its 0.1 mm

I got this from an unauthentic source but this meets the criteria about what our teacher told us.....even tho i think this paper might be fake but it's a good example of what's coming tomorrow for sure!
