How to Convert Decimeter to Earth's Polar Radius
1 dm = 1.57313035463093e-08 R_p
Example: convert 15 dm to R_p:
15 dm = 15 × 1.57313035463093e-08 R_p = 2.3596955319464e-07 R_p

Decimeter
A decimeter is a unit of length in the metric system, equal to one-tenth of a meter.
History/Origin
The prefix "deci-" comes from the Latin word "decimus," meaning tenth. The decimeter was part of the original metric system adopted in France in 1795.
Current Use
The decimeter is not as commonly used in everyday life as other metric units like the centimeter or meter, but it is sometimes used in technical and scientific contexts.
Earth's Polar Radius
The Earth's polar radius is the distance from the center of the Earth to the North or South Pole, approximately 6,356.8 kilometers.
History/Origin
The fact that the Earth is an oblate spheroid, flattened at the poles, has been known since the 18th century. Modern measurements are made with high precision.
Current Use
The Earth's polar radius is a key parameter in geodesy and is used to define the Earth's shape and gravitational field.
