A ken is a traditional Japanese unit of length equal to six shaku, approximately 1.818 meters, commonly used in architectural measurement and room dimensions.

What does Earth's polar radius represent?

Earth's polar radius is the distance from Earth's center to its geographic pole along the rotation axis and corresponds to the semi-minor axis of a geodetic ellipsoid like WGS84.

Why convert ken to Earth's polar radius?

Converting ken to Earth's polar radius helps relate traditional architectural units to global geodetic scales essential in mapping, satellite studies, and Earth science.

Tips & Best Practices

Confirm the precise definition of ken being used in calculations due to historical variations
Use conversions primarily for scientific, mapping, or comparative purposes where extremely small values are meaningful
Verify results when applying conversions in interdisciplinary contexts

Limitations

Ken is a traditional unit with slight historical variations, potentially affecting accuracy
Values converted to Earth's polar radius are extremely small, limiting everyday practical use
The vast difference in scale between units means interpretations should be context-specific
