What is a centiinch [cin]?

A centiinch is a nonstandard length equal to one hundredth of an inch, used mainly for specifying moderate-precision dimensions.

Why convert centiinch to Earth’s polar radius?

To relate very small length measurements in engineering or manufacturing to large geodetic scales useful in satellite and Earth-shape studies.

Is the centiinch an internationally recognized unit?

No, the centiinch is an informal unit primarily used in certain manufacturing and machining contexts.

Examples

100 centiinch [cin] converts to 3.9957355748e-9 Earth’s polar radius.
1,000 centiinch [cin] converts to 3.9957355748e-8 Earth’s polar radius.

Common Use Cases

Expressing moderate-precision engineering dimensions in geodetic terms.
Linking small manufacturing tolerances to large-scale Earth measurements.
Application in satellite orbit modelling and geospatial analysis.

Tips & Best Practices

Ensure units are accurately selected before conversion.
Understand that the centiinch is nonstandard and often informal.
Use converted values for geodesy and satellite studies rather than everyday measurements.

Limitations

The centiinch is not an internationally standardized unit, being informal in manufacturing contexts.
Earth’s polar radius is an extremely large measurement, so conversion yields very small results.
Device precision and rounding may affect accuracy when converting between such disparate scales.
