What is the area of a league or sitio in acres?

A league, which is a measurement of land area traditionally used in surveying, specifically in Texas and other parts of the southwestern United States, corresponds to approximately 4428.4 acres. This historical unit of measurement has roots in early land grants and surveys conducted during the colonial period. The league is based on the Spanish vara system and was defined as a square league measuring one league on each side, which results in an area of around 25 square kilometers or about 4428.4 acres when converted to the acre measurement.

Understanding the size of a league is essential for comprehending land measurement and allocation, particularly in the context of Texas land surveying, where this unit has significant historical relevance. This makes it important for surveyors to accurately interpret and apply these measurements when assessing land, particularly when dealing with older documents or land grants that utilize these traditional units.
