Circumference is the distance around an object. Most usually applied to a circle,

but any closed figure, building, octagon, etc, all have a circumference. Even a

non-regular object such as a tree or a meteor crater has a circumference. The

units used are entirely up to the measurer. Whether Imperial, SI, or whatever

you like, a circumference is always described in a unit of length.

What unit of measurement is used to measure the circumference of tree trunks?

Circumference is the measurement around the trunk of the tree. It is usually measured at breast height because trees flare out at the bottom at different rates based on soil conditions. The best way to measure this is with a ribbon or piece of rope. Diameter can be measured by dividing this number by pi or 3.1415
