This calculator allows you to convert from Chain to Earth's equatorial radius and in a reverse direction. To convert from Chain to Earth's equatorial radius, enter the amount of Chain into the first input and to convert from Earth's equatorial radius to Chain, enter the amount of Earth's equatorial radius into the second input.
25 Chain = 7.885032674E-5 Earth's equatorial radius
Chain to Meter | Chain to Foot | Chain to Centimeter | Chain to Inch | Chain to Kilometer | Chain to Mile | Chain to Millimeter | Chain to Yard | Chain to Micrometer |25 Chain equal 7.885032674E-5 Earth's equatorial radius.
Every 1 Chain = 3.1540130696E-6 Earth's equatorial radius and so, 25 Chain = 25 multiplied by 3.1540130696E-6 = 7.885032674E-5 Earth's equatorial radius.
What is the chain?
The chain is a unit of length. It equals 66 feet. The chain was first introduced between 1579 and 1607.
Several countries have used chain for several centuries especially in England. Note that there are 80 chains in one mile.
The main use of the chain is in laying out US townships. Official governments must use US survey chain to do surveys according to the federal law passed in 1785.
