   1 rod     = 25 links;    16.5  feet
   1 link    = 1/100 chain;  7.92 inches
   
   1 acre    = 10 square chains;  160 square rods; 4,840 square yards; 43,560 square feet; 
   1 hectare = 10,000 square meters;   
   
   1 acre    = approximately 0.4047 hectare; 
   i hectare = approximately 2.4711 acres;  
  
     25 links make a rod, pole or perch (16.5 feet).
    100 links make a chain.
   1000 links make a furlong.
   8000 links make a mile.

   The international foot is defined to be exactly    0.3048 meters 
   The international inch is defined to be exactly   25.4    millimeters
   The international mile is defined to be exactly 1609.344  meters

   1 US Survey Foot is  1200/3937 meter exactly (1893)
