-
Converting legacy survey data and cadastral maps defined in US survey units.
Tips & Best Practices
-
Verify which regional ell definition applies when working with historical data.
-
Use the converter for general translation between unit systems rather than exact precision.
-
Cross-reference converted values when dealing with high-precision surveying projects.
-
Consider the legacy nature of US survey inches when applying to modern measurements.
Limitations
-
Ell values varied regionally, so conversion involves approximate results.
-
The US survey inch has slight differences from the international inch affecting precise modern uses.
