Mm2 / Perche2 Units Definition
mm2 (Square milimeter)
Unit of area measurement equal to a square with a side of one millimeter. Abbreviations: mm2, mm².
Square perche
A square perch (often shortened to just a perch) is a unit of measurement and is equal to 25.29285264 square metres. Confusingly, a perch (not the squared
variety) is also called a rod or pole because it’s based on a surveyor’s tool
measuring exactly 5½ yards or 16½ feet or ¼ of a surveyor’s chain. The perch or rod was helpful tool and measurement for a surveyor because it could be used to create a ‘perfect’ acre of 40 perches by 4 perches – remember 160 perches equals an acre.
