What is a Roman actus?

A Roman actus is an ancient length unit roughly equal to 120 Roman feet or about 35.5 meters, used in land measurement and surveying in Roman times.

Why convert Roman actus to millimeters?

Converting to millimeters translates historic land measurements into a precise modern metric unit, aiding archaeology, history, and reconstruction work.

Is the conversion exact?

No, because the Roman actus is an approximate unit with differences based on historical foot lengths; conversions are close estimates.

Translating Roman cadastral field lengths into millimeters for precise reconstruction.
Using the conversion for historical land surveying and boundary documentation.
Expressing dimensions of Roman architecture components in modern units.
Supporting educational research by providing modern equivalents of Roman length units.

Tips & Best Practices

Verify whether millimeters suit your scale or if larger units like centimeters or meters are more practical.
Use the tool primarily for historical or academic contexts where ancient Roman units arise.
Be aware that Roman actus values are approximate and may vary depending on historical foot length interpretations.
Cross-check results if applying converted measurements to modern engineering standards.
Leverage example conversions to understand the scale differences between ancient and modern units.

Limitations

Roman actus is an approximate historical measure with some variability in exact length.
Very large millimeter numbers result from the conversion that may be unwieldy for practical use without converting further.
Regional or historical variations in Roman foot standards can affect precise conversion results.
