Question

Order 0.40 mm, 40 mm, 0.4 mm, and 0.004 mm from most to least precise

Answer 1

Is it just me, or are the first and third one the same thing?

Answer 2

Well, You would normally judge precision by the number of digits behind your decimal.

Answer 3

Yes, they're mostly the same. The only difference is that with 0.4, you have to guess at what's in the hundredth position, whereas in 0.40, you know what's in the hundredth position because it shows you, so 0.40 is more precise.

Answer 4

i believe its 0.004mm 0.40mm 0.4mm 0.40mm
