fill it with water.

measure the volume of water in cl.

divide that by the length in cm.

divide that by 3.14

average diameter

or

measure the outside diameter minus twice the material thickness.

or long nose vernier caliper.

I meant the inner diameter not the conical profile

Accuracy upto 2/3 decimal places

Decimal places is precision, accuracy is how close to the real value you want.

Unless you aren't telling us something else, then a digital caliper is probably good enough. If you're worried by out of round errors, take several readings of diameter and then average them.

Man who puts 5 shots in a 1 inch circle on the edge of a target is very precise.

Man who gets 5 shots in the Bulls eye is very accurate!.

A variation of 0.5 cm to 8 cm is pretty rough manufacturing if the diamater vairies that much.

Do you mean its a conical profile, or it may range in internal diameter from 0.5 to 8cm ? How accurately and precisely do you want to know ?
