-
Verify unit selection carefully to maintain accuracy in legal or cadastral data.
-
Use this converter to preserve consistency when dealing with historical land measurements.
-
Be cautious integrating these conversions with international units or modern GIS datasets.
-
Review large area aggregations for minor discrepancies due to slight conversion differences.
Limitations
-
The conversion rate of 1.000004 may cause small differences when working with extensive areas.
-
Minor discrepancies can occur when combining data with international standard units or modern mapping systems.
-
This tool focuses exclusively on U.S. Public Land Survey System units and may not apply globally.
Frequently Asked Questions
-
Why is the square mile (US survey) slightly different from the section unit?
-
The square mile (US survey) and the section are almost equal but differ by a factor of about 1.000004 due to the use of US survey feet in defining the square mile, resulting in a minimal size variation.
