How many "Chains" are in one Mile?

One mile is defined as 5,280 feet. In land surveying, a "chain" is a unit of measurement that equals 66 feet. To determine how many chains are in a mile, you divide the total number of feet in a mile by the number of feet in a chain.

So, if you take 5,280 feet and divide it by 66 feet (the length of one chain), you perform the following calculation:

5,280 feet ÷ 66 feet per chain = 80 chains.

This calculation confirms that there are indeed 80 chains in one mile, making it the correct answer. Understanding this conversion is crucial in land surveying as measurements often need to be converted between different units for various surveying methods and legal documents.
