What is Earth's polar radius?

Earth's polar radius is the distance from Earth's center to the mean geographic pole along the rotation axis, representing the semi-minor axis of a reference ellipsoid like WGS84.

What does centiinch [cin] stand for?

Centiinch [cin] is a nonstandard length unit equal to one hundredth of an inch, used for expressing finer-scale imperial dimensions.

Why convert Earth's polar radius to centiinch?

This conversion helps express large planetary measurements in finer imperial units for integration with engineering data measured in hundredths of an inch.

What Is This Tool?

This converter transforms values measured in Earth's polar radius, the semi-minor axis of the planet's reference ellipsoid, into centiinch [cin], a unit equal to one hundredth of an inch. The tool supports conversions across large geodetic distances and finer-scale imperial units used in engineering.

How to Use This Tool?

Enter the length value measured in Earth's polar radius in the input field.
Select Earth's polar radius as the input unit and centiinch [cin] as the output unit.
Click convert to obtain the equivalent length expressed in centiinch.
Review the result, which reflects the fine-scale imperial measurement corresponding to the geodetic input.

Key Features

Converts Earth's polar radius measurements into centiinch [cin], a subdivision of the inch.
Supports very large-to-fine scale length unit transformation.
Uses a defined conversion factor specific to WGS84 Earth's polar radius and centiinch.
Browser-based and easy to use without the need for additional software.

Examples

2 Earth's polar radius equals 50053362204.724 centiinch.
0.5 Earth's polar radius converts to 12513340551.181 centiinch.

Common Use Cases

In mapping and GPS to relate geodetic reference ellipsoid parameters to smaller imperial dimension units.
In satellite orbit modelling where distances measured in planetary radii need finer subdivision for engineering comparisons.
In manufacturing and tooling for converting large geodetic distances to detailed inch-based units useful for print and layout work.

Tips & Best Practices

Use the converter for contexts requiring comparison between large planetary scales and small precision units.
Be mindful of the large numeric results due to the size difference between Earth's polar radius and the centiinch.
Apply conversions when working with geodetic and engineering data that combine metric and imperial measurement systems.

Limitations

The centiinch [cin] is an informal, nonstandard unit not widely used internationally.
Conversions produce very large figures that may be difficult to interpret practically.
Use cases for this conversion are limited to specific niche applications due to the extreme unit scale difference.
