What is a Roman actus?

The Roman actus is an ancient Roman measurement of length equal to 120 Roman feet, approximately 35.5 meters, used mainly in Roman land surveying and defining land area.

A parsec is an astronomical length unit equal to about 3.085677581×10^16 meters, used to express distances between stars and other celestial objects.

Why convert Roman actus to parsec?

This conversion enables linking ancient terrestrial measurements with astronomical distances, useful in archaeoastronomy, historical cartography, and scientific studies comparing scales.

Examples

10 Roman actus equals 1.1497870099987e-14 parsec [pc]
100 Roman actus equals 1.1497870099987e-13 parsec [pc]

Common Use Cases

Translating ancient Roman land measurements into astronomical distance units
Studying relationships between terrestrial surveying units and cosmic distances
Applying in archaeoastronomy and historical cartography research

Tips & Best Practices

Ensure correct unit selection for accurate conversions
Use this tool primarily for academic or illustrative purposes given scale differences
Cross-reference with historical and astronomical data when conducting research

Limitations

Roman actus is a small, ancient unit mainly relevant to regional historical contexts
Due to vast scale differences, converted values are extremely small and rarely practical in standard astronomy
Conversions serve mostly illustrative or academic comparisons rather than precise measurements
