Earth Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator. It represents the Earth's radius measured along the equatorial plane.
Its value is approximately 6,378.1 kilometers (about 3,963.2 miles).
The Earth is not a perfect sphere but an oblate spheroid, so the equatorial radius is slightly larger than the polar radius.
This radius is important for geodesy, satellite orbits, and mapping.
Key facts:
Equatorial radius ≈ 6,378.1 km
Larger than polar radius due to Earth's flattening at the poles
Used in Earth sciences, navigation, and space missions
Understanding the Earth's equatorial radius helps in accurate modeling of the planet’s shape and gravitational field.
Finger (Cloth)
A finger is a traditional, informal unit of length based on the width of a human finger. It was commonly used in tailoring and cloth measurement. The exact length varies but is generally considered to be about ¾ inch (approximately 1.9 centimeters).
The finger measurement helped tailors and fabric merchants make quick estimations of small lengths or widths of material before precise tools were common. It is one of several body-based units used historically in textiles, alongside the span, palm, and hand.
Though rarely used in modern measurement, the finger remains a part of historical measurement systems and illustrates how people relied on their bodies for everyday measuring tasks.
Summary:
1 finger ≈ ¾ inch (1.9 cm)
Based on the width of a human finger
Used in tailoring and cloth measurement
Mostly of historical interest today
