Yeah I only use calipers and micrometers for machining--I haven found any use for additive manufacturing--and never in metric units because all my tools are imperial. Just strange the calipers punish metric users by giving them only half the precision.

If you buy a tool in a country that is mainly using imperial, the markings on it might be more exact for the imperial measurement. Might be the opposite in a country with metric. Just guessing though but that is often how other things work out.

A Google image search for "caliper" shows several have 0.001in and 0.02mm accuracy, which is similar.

For 0.01mm there are only electronic or dial calipers.
