Earth Polar Radius

The Earth's polar radius is the distance from the center of the Earth to the North or South Pole. It measures the Earth’s radius along its rotational axis.

Its value is approximately 6,356.8 kilometers (about 3,949.9 miles).
The Earth is an oblate spheroid, so the polar radius is slightly shorter than the equatorial radius due to the planet's flattening at the poles.
This measurement is crucial for geodesy, understanding Earth’s shape, and satellite navigation.

Key facts:

Polar radius ≈ 6,356.8 km
Smaller than equatorial radius by about 21.3 km
Important for precise Earth modeling and mapping

The difference between the polar and equatorial radius reflects the Earth’s rotation and its effect on the planet’s shape.

Long Cubit

The long cubit is an ancient unit of length that is a variation of the standard cubit, measuring from the elbow to the tip of the middle finger. The long cubit is longer than the common cubit, typically about 21 inches (approximately 53 centimeters).

It was used in ancient civilizations such as Egypt and Mesopotamia for construction, land measurement, and crafts, especially when more precision or a larger unit was needed.

Key points:

Long cubit ≈ 21 inches (53 cm)
Longer than the standard cubit (usually about 18 inches)
Used in ancient architecture and surveying
Provided a larger base unit for measurements in construction

The long cubit helped ancient builders and surveyors manage larger scales while still relying on the human body as a reference.
