What is a circular inch?

A circular inch is the area of a circle with a diameter of one inch, equal to π/4 square inches, used mainly for round object cross-sectional areas.

What is the barn unit used for?

The barn is a tiny unit of area used mainly in nuclear and particle physics to express cross-sectional areas in scattering and reaction processes.
