Please provide values below to convert hectometer [hm] to Earth's equatorial radius [R_e], or Convert Earth's equatorial radius to hectometer.
How to Convert Hectometer to Earth's Equatorial Radius
1 hm = 1.5678559428874e-05 R_e
Example: convert 15 hm to R_e:
15 hm = 15 × 1.5678559428874e-05 R_e = 0.00023517839143311 R_e
Hectometer to Earth's Equatorial Radius Conversion Table

Hectometer
A hectometer is a unit of length in the metric system equal to 100 meters.
History/Origin
The prefix "hecto-" from the Greek "hekaton" meaning hundred, was part of the original metric system adopted in France in 1795.
Current Use
The hectometer is not a widely used unit of length in English-speaking countries. It is sometimes used in surveying and for marking distances on highways in some countries.
Earth's Equatorial Radius
The Earth's equatorial radius is the distance from the center of the Earth to the equator, approximately 6,378.1 kilometers.
History/Origin
The size and shape of the Earth have been a subject of study since ancient times. Modern measurements are made using satellite geodesy.
Current Use
The Earth's equatorial radius is a fundamental parameter in geodesy, geophysics, and astronomy. It is used in cartography and for defining the shape of the Earth.
