Neither is necessarily more precise; something could be exactly 19mm or exactly 2cm. However it can definitely be said that measuring to the nearest mm is more precise than measuring to the nearest cm. This is because a mm is smaller and so if any rounding is involved (to the nearest mm or cm) then the rounding is less of a distance and the error in absolute precision is therefore less.
19mm
612 m is more precise.
The word accurate is a synonym for precise. So the most accurate (or precise) answer would be 57.213 because it is more accurate if the number is not rounded.
Divide it by 25.4
You. Or your remainders, to be more precise.
19mm
19mm is more precise. 19mm = 1.9cm
2cm
19mm
The smallest centimetre is 2cm because 342cm is 340 spaces more than 2cm
2cm*2cm*2cm
2cm*2cm*2cm = 8cm3
A cube has all sides of length 2cm. What is the surface area and volume of the cube?
cups is less precise.
19mm is 0.019 meters.
