What is Earth's polar radius?

Earth's polar radius is the distance from the 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 'finger (cloth)' measure?

Finger (cloth) is an informal, traditional length unit based on the breadth of a human finger, used mainly in tailoring and textile work for approximate measurements.

Why convert such vastly different units?

Conversions between Earth's polar radius and finger (cloth) are mainly used for educational, comparative, or illustrative purposes to connect scientific geodesy and traditional textile measurements.

Click the convert button to get the result in finger (cloth).
Review the conversion example to understand the scale difference.

Key Features

Converts between a highly precise scientific length and an informal textile measurement.
Supports illustrative and comparative conversions involving vastly different scales.
Ideal for educational demonstrations linking geodesy and traditional units.
Includes practical examples showing how to perform the conversions easily.

Examples

Convert 2 Earth's polar radius to finger (cloth): 2 × 55614846.894137 = 111229693.788274 finger (cloth).
Convert 0.5 Earth's polar radius to finger (cloth): 0.5 × 55614846.894137 = 27807423.4470685 finger (cloth).

Common Use Cases

Defining the semi-minor axis of geodetic reference ellipsoids for mapping and GPS.
Making informal fabric measurements during tailoring and garment alterations.
Using in educational contexts to illustrate differences between scientific and traditional units.
Interpreting historical textile measurements recorded without standardized units.

Tips & Best Practices

Use this converter mainly for qualitative or educational purposes due to the informal nature of finger (cloth).
Cross-check conversions if applying in textile contexts since finger sizes vary widely.
Understand that the conversion bridges two vastly different scales and units.
Refer to examples to gain a practical sense of the magnitude differences.

Limitations

Finger (cloth) is a non-standard, variable unit based on individual finger breadths and historical usage.
The presence of vast scale differences limits practical applications of this conversion.
Conversions serve mostly illustrative or qualitative purposes rather than precise engineering needs.
Due to its informal nature, exact precision in conversion is not achievable.
