Question

What would be more accurate: measuring to the nearest millimeter or to the nearest eighth of an inch?

Answer 1

Measuring to the nearest millimeter will be more accurate.

Explanation:

An inch has `2.54` `cm` or `25.4` `mm`

and hence one eighth of an inch is `25.4/8=3.175` `mm`,

which is more than thrice the nearest millimeter.

Hence, measuring to the nearest millimeter will be more accurate.
