What is a Roman actus?

It's an ancient Roman unit of length, roughly 35.5 meters, originally used in land measurement and cadastral surveys.

Why does the long reed vary in length?

The long reed's size differed by local traditions and historical periods, so its exact length is not consistent.

Can this tool be used for precise engineering work?

No, due to the variability of historical units, it's intended for historical interpretation rather than precise modern measurements.

How do I convert long reeds back to Roman actus?

This tool focuses on Roman actus to long reed conversion; inverse conversions require using the reciprocal of the stated rate.

Translating ancient Roman land measurements for academic or archaeological studies
Interpreting historical local land distance units in maps and cadastral records
Supporting restoration projects involving old property boundaries
Bridging Roman cadastral data with regional surveying practices
Facilitating research in historical anthropology and metrology

Tips & Best Practices

Always consider the historical context as the long reed length varied by region and era
Use this tool for interpretative research rather than precise engineering measurements
Cross-reference historical documents when possible to ensure accurate unit interpretation
Convert results into SI units for modern scientific or technical applications after using this tool
Understand that original Roman surveying was based on their own foot measure influencing unit size

Limitations

The long reed unit size is not fixed and differs historically depending on locality
Conversion should be treated as approximate due to regional and temporal variations
Not intended for precise modern engineering or scientific calculations
Historical record discrepancies may affect the accuracy of conversions
Modern project requirements should use standardized SI units after conversion
