Perche2 / Dm2 Units Definition
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.
dm2 (Square decimeter)
Therefore, a square decimeter (or "square decimeter" in British spelling) is one tenth of a square meter. It can also be expressed by ten square centimeters. A rough example of a decimeter could be the average surface area of some smartphone screens.
