Square Rod (sq rd, rd2) The area of a square measuring one rod (16.5 feet) on a side. One sq rod = 272.5 sq feet = 25.292 852 64 sq meters. Uncommon unit. Acre (acre) The area of a square measuring approximately 209 feet on a side. 1 acre = 43,560 square feet = 4046.856 422 4 sq meters = 0.404 685 642 24 hectares. Quarter Section (  ) The area of a square measuring 0.5 mile (2,640 feet) on a side. Four quarter sections make up one section, which is equivalent to one square mile. One quarter section = 160 acres = 0.648 sq kilometers = 6.9 million sq feet. Square Mile (sq mi, mi2) The area of a square measuring one mile (5,280 feet) on a side. Also called a section. One sq mile = 640 acres = 2.589 988 110 336 sq kilometers = 27 million sq feet = 4 quarter sections. Square Millimeter (sq mm, mm2) The area of a square measuring one millimeter (0.001 meters) on a side. One sq mm = 0.01 sq centimeters = 0.00155 sq inches. Square Centimeter (sq cm, cm2) The area of a square measuring one centimeter (0.01 meters) on a side. One sq cm = 100 sq millimeters = 0.155 sq inches. Square Meter (sq m, m2) The area of a square measuring one meter on a side. One sq m = 10.764 sq feet = 1.196 sq yards = 0.0001 ares. Are (a) The area of a square measuring ten meters on a side. One are = 1076 sq feet = 100 sq meters = 0.01 hectares = 0.0247105 acres. Hectare (ha) The area of a square measuring 100 meters on a side. One hectare = 2.47 acres = 10,000 sq meters = 0.01 sq kilometers. Square Kilometers (sq km, km2) The area of a square measuring one kilometer on a side. One sq km = 247 acres = 100 hectares = 10,763,910 sq feet = 0.386 sq miles.
