What is the Earth's equatorial radius used for?

It defines reference ellipsoids and map projections in geodesy, assists in satellite orbit calculations, and helps convert between geodetic and geocentric coordinates.

What does the long cubit measure?

The long cubit is a historical length unit ranging roughly from 20.5 to 22.5 inches, commonly used in ancient Near Eastern and Egyptian systems.

Why convert Earth's equatorial radius to long cubits?

Converting enables interpreting modern geodetic data in ancient units, supporting archaeological analysis, historical reconstructions, and museum exhibits.

Examples

0.5 Earth's equatorial radius converts to approximately 5,978,777.65 long cubits.
2 Earth's equatorial radii convert to about 23,915,110.61 long cubits.

Common Use Cases

Translating modern Earth geodetic measurements into historical units for archaeology.
Reconstructing dimensions of ancient structures or artifacts from historical texts.
Converting measurements for museum labeling or creating replicas using original units.

Tips & Best Practices

Use this tool primarily for large-scale or theoretical conversions given the size difference between units.
Apply the conversion carefully considering that the long cubit varies by region and period.
Utilize the results as approximate values aligned with average estimations of the long cubit.

Limitations

The long cubit's size varies historically, so results represent an average approximation.
Detail-level precision may be limited due to variability in the ancient measurement unit.
This conversion is better suited for conceptual or educational usages than precise engineering.
