What is the Earth's equatorial radius?

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

What is a ken and where is it used?

Ken is a traditional Japanese unit of length equal to six shaku, used primarily in architecture to define bay widths and room dimensions.

Can this conversion be used for daily measurements?

No, due to the large difference in scale, this conversion is mostly academic or theoretical rather than practical.

What Is This Tool?

This tool converts distances measured in Earth's equatorial radius units to ken, a traditional Japanese length measure used mainly in architecture. It provides an easy way to translate very large geodetic distances into modular units relevant for cultural and scientific contexts.

How to Use This Tool?

Enter the value expressed in Earth's equatorial radius units.
Select the output unit as ken.
Click convert to get the equivalent length in ken.

Key Features

Convert between Earth's equatorial radius and ken with a precise conversion factor.
Browser-based and easy to use without any installations.
Ideal for applications in geodesy, aerospace, Japanese architecture, and interdisciplinary studies.

Examples

0.5 Earth's equatorial radius equals 1,505,447.61 ken.
2 Earth's equatorial radius equals 6,021,790.44 ken.

Common Use Cases

Defining reference ellipsoids and map projections in geodesy and cartography.
Calculating satellite orbits and ground tracks in aerospace engineering.
Expressing traditional Japanese architectural bay widths and room dimensions.
Converting geodetic distances for comparative academic research involving traditional units.

Tips & Best Practices

Use the tool for theoretical or academic conversions rather than practical measurements.
Understand that ken is a small unit, so the converted values can be very large.
Verify usage context when applying converted lengths in interdisciplinary studies.

Limitations

Earth's equatorial radius is extremely large compared to ken, making the conversion mainly theoretical.
Rounding in values and historical variations in ken length may affect conversion accuracy.
