What is Earth's equatorial radius used for?

It serves as a standard geodetic measurement for defining Earth’s shape, aiding geodesy, cartography, and aerospace calculations.

Why convert Earth's equatorial radius to inches?

Converting to inches allows use in contexts requiring imperial units, such as U.S. manufacturing and engineering design.

Are conversions exact for all Earth measurements?

No, this conversion applies only to the standard Earth's equatorial radius value, not variations in local radius.

Examples

1 Earth's equatorial radius equals 251,108,661.42 in.
0.5 Earth's equatorial radius converts to 125,554,330.71 in.

Common Use Cases

Defining reference ellipsoids and map projections in geodesy and cartography.
Calculating satellite orbits, ground tracks, and range computations in aerospace engineering.
Expressing large-scale Earth measurements in inches for design and manufacturing documentation.

Tips & Best Practices

Use this tool when precise conversions of Earth's equatorial radius to inches are required in imperial units.
Remember that inches are typically for smaller scales, so handle large resulting values carefully.
Confirm unit selections before converting to ensure accuracy in your application context.

Limitations

Conversion is exact only for the Earth's equatorial radius as defined by the WGS84 standard; local radius variations are not accounted for.
Inch units are usually intended for small distances, so large planetary-scale distances expressed in inches can be unwieldy.
The tool does not account for any measurement uncertainties beyond the standard geodetic value.
