How Many Feet in a Chain?

A chain is a unit of length that plays a crucial role in surveying and land measurement. It is a part of both the imperial and US customary systems, consisting of precisely 66 feet. This unit is often used to measure distances between survey markers, fence lines, or other linear features.

Conversion to Feet:

To convert chains into feet, one simply needs to apply the fact that a chain is equal to 66 feet. This conversion can be expressed as:

  • 1 chain = 66 feet

FAQs (Frequently Asked Questions):

Why is the chain used as a unit of measurement?

The chain is historically significant for surveying and land measurement due to its practical length for measuring distances between survey markers and defining property boundaries.

In what scenarios might I need to convert between chains and feet?

Converting between chains and feet is necessary when working with maps, land surveys, or fencing projects. It facilitates a clear understanding of distances in different contexts.

Can I convert from feet to chains by dividing?

Yes, you can. Since 1 chain equals 66 feet, dividing the number of feet by 66 will provide the equivalent measurement in chains.

Is the chain still widely used in modern surveying?

While electronic measuring tools are common in modern surveying, the chain’s historical significance has left a lasting impact on land measurement terminology and methodology.


In conclusion, a chain is a valuable unit of length, equal to precisely 66 feet, traditionally employed in surveying, land measurement, and fencing projects. The conversion factor of 1 chain to 66 feet is essential for interpreting distances on maps or in surveys and determining the correct amount of fencing material for installation. Understanding the relationship between chains and feet remains relevant today, bridging the historical legacy of land measurement with contemporary applications in construction and surveying.
