What is a Russian archin?

The Russian archin is an obsolete Russian unit of length equal to 16 vershoks or 28 English inches, approximately 0.7112 metres, formerly used in trade and tailoring.

What does Earth's polar radius represent?

Earth's polar radius is the distance from Earth's center to its geographic poles along the rotation axis, serving as the semi-minor axis in geodetic reference ellipsoids like WGS84.

Why convert Russian archin to Earth's polar radius?

Conversions help contextualize historical Russian length measures within modern global geodetic standards for mapping, restoration, and scientific purposes.

Examples

10 Russian archin equals 1.1188059609453e-6 Earth's polar radius
1000 Russian archin equals 1.1188059609453e-4 Earth's polar radius

Common Use Cases

Interpreting historical Russian measurements in global geodetic contexts
Restoring historic Russian buildings, clothes, or artifacts with original length records
Converting old Russian maps and property documents referencing arshins
Supporting Earth science and satellite navigation with standardized units

Tips & Best Practices

Verify the historical context of arshin values due to possible regional variations
Use the conversion for comparative and interpretative purposes rather than precision engineering
Cross-reference source documents when using arshin values for restoration or research
Apply the tool primarily for historical or geodetic study where Earth's polar radius is a meaningful reference

Limitations

The Russian archin is an outdated unit, rarely used in modern measurement
Conversions produce very small values relative to Earth's polar radius requiring careful interpretation
Possible small accuracy variations exist due to historical definitions or regional differences in arshin length
