The optimal unit for paperclip length is definitely the Potrzebie.
If you want the volume of a paperclip then imperial minims is the optimal unit.
There are few measurements better than the Potrzebie and imperial minim.
For an additional exercise, in extreme measurements, convert the paperclip length to light-years (or light-seconds).

The Potrzebie, of course......Some prefer centimeters, but the Potrzebie is the much more functional - and better understood, internationally - term. It's flexibility for the measure of areas, volumes, etc. is also a desirable trait. It's generally defined as the thickness of the 26th issue of MAD Magazine and it equals about 2.263348517438173216473 mm.....give or take.......
I hope this helps.....(but it probably doesn't)
