Civil Engineering tool for Surveying Chain tape:
The chain tape is also referred to as the Günter’s chain. Gunter’s chain, the 300 –year-old measuring instrument by which all survey measurement in the English – speaking countries and much of it elsewhere was done. It has been superseded by the steel tape and electronic equipment. Gunter’s chain is 66 feet long; 80 chain equal to one mile, and 10 square chains equals an acre. The chain is subdivided into 100 links. A rod or perch was 25 links. Each link was a short section of wire connected to the next by a loop. At each end of the chain was a brass handle. The 66 – foot unit is still called a chain and is still in use in property descriptions and in the public land system. The Gunter chain is generally used in taking short and detailed length and breadth of a school farmstead.
