What Is This Tool?
This tool allows you to convert length values from vara castellana, a historical Spanish unit of measure, to chain (US survey), a traditional U.S. land surveying unit. It is designed to help users interpret historical land measurements and cadastral records by translating these units accurately for modern applications.
How to Use This Tool?
-
Enter the length value in vara castellana you wish to convert.
-
Select vara castellana as the input unit and chain (US survey) as the output unit.
-
Submit the value to get the equivalent measurement in chain (US survey).
-
Use the result for mapping, legal analysis, or historical interpretation.
