How Many Chains in a Mile?

A chain, a unit of length equal to 66 feet, serves as a practical measurement tool in various applications. In contrast, a mile, a widely recognized unit of length, comprises 5,280 feet. This relationship allows us to establish a straightforward conversion factor: 1 mile is equivalent to 80 chains.

This conversion can be expressed as:

  • 1 mile = 80 chains

Here is a table showing the conversion between miles and chains:

Miles Chains
1 80
2 160
3 240
4 320
5 400
6 480
7 560
8 640
9 720
10 800

FAQs (Frequently Asked Questions):

Why is the chain used as a unit of measurement?

Chains have been historically valuable for surveying, land measurement, and other applications due to their practical length for measuring distances and defining property boundaries.

When might I need to convert between miles and chains?

Conversion between miles and chains is essential when working with maps, land surveys, or other measurement scenarios, enabling a clear understanding of distances in different contexts.

Can I calculate the number of chains directly from miles by multiplying?

Yes, you can. Since 1 mile equals 80 chains, multiplying the number of miles by 80 will yield the equivalent measurement in chains.

Is the chain still relevant in modern surveying and construction?

While modern surveying often uses electronic measuring tools, the chain’s historical significance persists in land measurement terminology and methodology.


In conclusion, a chain, equivalent to 66 feet, and a mile, comprising 5,280 feet, hold distinct places in the realm of length measurement. The conversion factor of 1 mile equating to 80 chains bridges these units, facilitating clear transitions between miles and chains. This conversion is valuable when interpreting maps, surveys, or other measurements, offering a versatile tool for understanding distances across various applications, from navigation to land surveying.
