What is the Earth's equatorial radius?

It is the straight-line distance from the Earth's center to the equator measured along the equatorial plane, defined as 6,378.137 kilometers.

What is the X-unit [X] used for?

The X-unit is a historical length unit used in X-ray crystallography and spectroscopy to express X-ray wavelengths and interatomic spacings.

Why convert from Earth's equatorial radius to X-unit?

Such conversions assist in scientific analyses that compare geodetic measurements with atomic-scale X-ray data or for interpreting historical research.

Supports interdisciplinary scientific and historical data use.
Browser-based and easy to use without complex formulas.
Utilizes the standardized conversion rate defined by geodesy and crystallography references.

Examples

1 Earth's equatorial radius equals 6.364920964394 × 10^19 X-unit [X].
0.5 Earth's equatorial radius equals 3.182460482197 × 10^19 X-unit [X].

Common Use Cases

Defining geodetic reference ellipsoids and map projections.
Calculating satellite orbits and ground track parameters.
Converting Earth measurement data for comparison with X-ray crystallography results.
Analyzing historical scientific data involving lattice plane spacings and X-ray wavelengths.

Tips & Best Practices

Verify the context of conversion since it bridges vastly different measurement scales.
Use this conversion primarily for theoretical or comparative scientific studies.
Understand the limitations of historical units versus modern SI units for precision.

Limitations

The units measure vastly different scales: macroscopic Earth distances vs atomic-scale X-ray wavelengths.
Conversion is mainly theoretical and not suited for practical, direct applications.
Historical nature of the X-unit means it is largely replaced by SI units like the ångström or picometer.
