One chain = 66 survey feet.
A shackle is a unit of measure of anchor chains which is equal to 90 feet.
There is no such unit of measurement as an anchor - if you are thinking of acre, this is a unit of area, not of length, and therefore the two units are incompatible.
A chain is a very old Linear Measure. 1 chain = 22 yards = 66 feet.

Technically there is no exact number if I'm getting your question right. A "rode" is a generic term normally applied to the anchor line on a ship and refers to the amount of chain rope or cable that the boat carrys. In common useage on board a ship you might hear a person say something like "we carry 200 fathoms of wire and 80 feet of chain on our anchor rode".
66 feet
One chain = 66 survey feet.
the length should be 8 times the depth of the deepest water you are planning to anchor in.
1 shackle = 15 fathoms = 90 feet A unit of length used for anchor chain on ships. Anchor chains for ships are made up of 15-fathom lengths of chain joined by detachable links. The joins are distinctively marked so a ship's officer can estimate at a glance how much chain is out. In the merchant marine, the detachable links are painted red. At 15 fathoms, the end of the first shot, the two links on either side of the detachable link are painted white, and 1 turn of wire is wound around the stud of the link on either side of the detachable link. At 30 fathoms, the 2 links on either side of the detachable link are painted white, and 2 turns of wire are put on the second stud on either side of detachable link, and so on for the remaining shots. In the merchant marine, in the command to let go the anchor the amount to be played out is given in shots; in the Navy it is given in fathoms.1
