Current Use
Today, the circular inch is primarily used in niche applications such as engineering and manufacturing where circular area measurements are relevant, but it remains a rarely used unit outside specialized contexts.
Square Perch
A square perch is a unit of area measurement equal to the area of a square with one perch (16.5 feet) on each side.
History/Origin
The square perch, also known as a square rod or perche, originated in the British Imperial system and was traditionally used in land measurement, especially in the UK and former British colonies.
