Accurate linear measurement.
by dividing diameter by 2 :)
A rulerDepending on the degree of accuracy required: a ruler, vernier callipers, micrometer.
Vernier callipers are made in various sizes. The range would depend on the size. The most usual size is 0 - 150 mm
How much error is allowed in a digital vernier
No
Because they were invented by Pierre Vernier in 1631.
4
Pythagoras
yes it is 2.25

I would use vernier callipers.
To measure things, or is that just too obvious? A.K.A. Vernier Callipers
in order to get the result in mm or cm
0.1mm It is the range of verniercalliper. As it has least count 0.1mm that's why its range is 0.1 mm in physics laboratory
