Linear Measure
12 inches (in.) = 1 foot (ft.)
3 feet = 1 yard (yd)
51/2 yards = 1 rod (rd), pole, or perch (161/2 ft.)
40 rods = 1 furlong (fur) = 220 yds = 660 ft.
8 furlongs = 1 statute mile (mi.) = 1,760 yds
= 5,280 ft.
3 land miles = 1 league
5,280 feet = 1 statute or land mile
6,076.11549 feet = 1 international nautical mile
 
Area Measure
144 square inches = 1 sq ft.
9 square feet = 1 sq yd = 1,296 sq in.
301/4 square yards = 1 sq rd = 2721/4 sq ft.
160 square rods = 1 acre = 4,840 sq yds
= 43,560 sq ft.
640 acres = 1 sq mi.
1 mile square = 1 section (of land)
6 miles square = 1 township = 36 sections
= 36 sq mi.
 
Cubic Measure
