An engineer or scientist.
I would use a micrometer. A caliper would do as well.
Micrometer to measure the accuracy of 0.01 mm. Caliper to measure with accuracy of 0.1 mm is used.
With a micrometer (caliper) To measure the thinkness you use mm's
Caliper. Micrometer
A vernier caliper would be a good way, unless you need a more accurate measurement, in which case I might use a micrometer caliper.
A machinist such as a lathe operator would use a micrometer caliper for precise measurements of the product he is machining, Also used by designers of precision parts and programmers of precision machines.

A micrometer caliper is a measuring device for finding very exact measurements of an item. The least count of a micrometer caliper in millimeter is 0.02.
A meter stick caliper is very large and would make general measurements. A micrometer caliper is much smaller and can be used to make much smaller measurements.
micrometer is more occurate.
If you have to measure the pencil to a couple decimal places i would suggest a micrometer and a dial caliper.
