This calculator allows you to convert from Chain to Earth's polar radius and in a reverse direction. To convert from Chain to Earth's polar radius, enter the amount of Chain into the first input and to convert from Earth's polar radius to Chain, enter the amount of Earth's polar radius into the second input.
250 Chain = 0.00079115564381133 Earth's polar 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 |250 Chain equal 0.00079115564381133 Earth's polar radius.
Every 1 Chain = 3.1646225752453E-6 Earth's polar radius and so, 250 Chain = 250 multiplied by 3.1646225752453E-6 = 0.00079115564381133 Earth's polar 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.
