US survey rod (rdUS). The US survey rod is 16.5 US survey feet, about 5.0292 m.
US survey chain (chUS). The US survey chain is 66 US survey feet, about 20.1168 m.
There are 0.25 US survey chains in one US survey rod.
Multiply the number of US survey rods by 0.25. For example, 10 US survey rods equal 2.5 US survey chains.
One US survey chain equals 4 US survey rods.
3 US survey chains. Other common values: 5 US survey rods = 1.25 US survey chains and 100 US survey rods = 25 US survey chains.
