What is the Earth's equatorial radius?

It is the distance from Earth's center to the equator along the equatorial plane, standardized at 6,378.137 kilometers.

What does cubit (UK) represent?

Cubit (UK) is a historical length based roughly on the distance from the elbow to the tip of the middle finger, commonly about 18 inches or 45.72 cm.

Can I use this conversion for precise engineering work?

No, this conversion is mostly symbolic or educational due to the non-standardized nature of the cubit.
