Builders measurements can be converted to Surveyor's measurements with the calculator below:

Some units of measurement used in past and present surveys:

• 1 meter = 39.37 in = 3.2808 ft
• 1 rod = 1 pole = 1 perch = 16½ ft = 5.029 m
• 1 engineer’s chain = 100 ft = 100 links = 30.48 m
• 1 Gunter’s chain = 66 ft = 20.11 m = 100 Gunter’s links (lk) = 4 rods
• 1 acre = 100000 sq (Gunter’s) links = 43560 ft² = 160 rods² = 10 sq (Gunter’s) chains = 4046.87 m² = 0.4047 ha
• 1 rood = 3/4 acre = 1011.5 m² = 40 rods²
• 1 ha = 10000 m² = 107639.10 ft² = 2.471 acres
• 1 arpent = about 0.85 acre
• 1 square arpent about 3439.1 m²
• 1 statute mi = 5280 ft = 1609.35 m
• 1 mi² = 640 acres = 258.94 ha
• 1 nautical mi (U.S.) = 6080.27 ft = 1853.248 m
• 1 fathom = 6 ft = 1.829 m
• 1 cubit = 18 in = 0.457 m
• 1 vara = 33 in
