About the perch

The perch, also called the rod or pole, is a length of 16.5 ft, and as an area unit a perch means one square rod: 272.25 sq ft, 30.25 sq yd or about 25.29 m². Forty perches make a rood and 160 make an acre.

Sri Lanka still measures land customarily in perches, so house plots there are sold as, say, “10 perches” (2,722.5 sq ft). The revenue marla of Punjab is exactly the same area, a legacy of the same British standard.
