What is a square rod (US survey)?

It is an area measurement defined as the area of a square with sides of one US survey rod, equivalent to 272.25 square US survey feet.

What does square mil [mil^2] represent?

It is the area of a square with a side length of one mil (0.001 inch), used for very small areas in electronics and precision manufacturing.

Can I confuse square mil with circular mil?

No, the square mil measures a square’s area, whereas the circular mil refers to the area of a circle with a 1 mil diameter; they are different units.
