A chain is a unit of length. An acre is a unit of area. The two units are therefore incompatible.
0.09 acre = 0.9 square chains
Their are 10 Square chains in an acre see http://www.answers.com/topic/chain-unit for more details
10 square chains = one acre
An acre's breadth is a historical term for a chain - the width of a single acre, which is defined as 10 square chains.
Each side of a square with an area of 10 acres measures: 10 chains in length.
One acre equals 10 square chains.
1 furlong = 10 chains 1 acre = 1 furlong x 1 chain = 1 furlong x 0.1 furlong = 0.1 sq furlong.
an acre is 1 chain by 10 chains 1 chain = 22 yards or 66 feet (66ft x 0.3048m/ft)2 x 10 = 4,046.856 square metres
Just over 1 at 46200 sq. ft. 43,560 sq ft = 1 acre.
How many centimeters are in a acre
There were several versions of measuring chains in history, but the most popular for the last 400 years was the Gunter's chain, measuring 66 feet, having 100 links. The 66-foot measurement has the interesting characteristic that it is the square root of 4356, which is 1/10 of the number of square feet in an acre. Thus, ten square chains is on acre. Obviously, a mile is also composed of 80 chains (5280/66). Many land surveys into the 20th century continued to use chains in the USA, as well as rods, which is exactly 1/4 of a chain.
An acre is an area of 1 furlong * 1 chain ( 220 yds * 22 yds ) A chain is a measure of length only = 22 yds
