0.5 Roman actus equals 698.3986032 inch (US survey).
Common Use Cases
-
Analyzing ancient Roman cadastral and agricultural surveying measurements.
-
Interpreting Roman land records and distances for archaeological research.
-
Converting legacy U.S. survey and cadastral data for modern engineering projects.
-
Restoring cadastral surveying data involving Roman units and US survey units.

Tips & Best Practices
-
Remember that the Roman actus is approximate and varied historically.
-
Consider differences between the US survey inch and the modern international inch.
-
Use this tool for comparison and archiving of historical and legacy measurement data.
-
Verify the context of measurements when applying conversions to avoid errors.
-
Combine this conversion with domain expertise in surveying or archaeology.
Limitations
-
Roman actus measurements can differ by location and period, creating some uncertainty.
-
The inch (US survey) differs from the international inch and is a fixed legacy unit.
-
Historical measurement variability should be accounted for in analyses.
-
This tool does not adjust for differences between modern and legacy units beyond conversion.
Frequently Asked Questions
-
What is a Roman actus used for?
-
It was an ancient Roman unit of length used primarily in surveying and land measurement, especially for recording field lengths and defining land areas.
-
How is an inch (US survey) defined?
-
The inch in the US survey system equals exactly 1/12 of a US survey foot, defined as 100/3937 meters, and was used in historic US surveying and mapping.
-
Can I convert Roman actus to modern inches?
-
This tool converts Roman actus to the US survey inch, a legacy unit. Conversions to modern international inches may require additional adjustments.
