What exactly is a long cubit?

A long cubit is an ancient unit of length used in Near Eastern and Egyptian cultures, generally around 20.5 to 22.5 inches (approximately 52 to 57 cm), often associated with the royal cubit.

Why convert long cubits to Earth's equatorial radius?

This conversion enables integration of ancient length measurements with modern geodetic and earth science frameworks, useful in archaeology, geodesy, and aerospace engineering.

Are the conversion results exact?

No, conversions involve approximations due to varying long cubit values over history and use of Earth's average equatorial radius, so results are best for general reference and interdisciplinary study.
