-
The Russian archin is an obsolete unit and rarely used in modern contexts
-
Conversion relevance depends on context-specific knowledge of both units
Frequently Asked Questions
-
What is the Russian archin?
-
The Russian archin is an obsolete Russian length unit equal to 16 vershoks or about 0.7112 meters, used previously for measuring textiles and lengths in trade and crafts.
-
Why convert Russian archin to Bohr radius?
-
This conversion helps translate historical measurements into atomic units used in quantum chemistry and physics for multidisciplinary research and preservation.
-
Are the conversion results practical for everyday use?
-
No, due to the dramatic scale difference, the converted values become very large and are mainly useful in scientific or specialized contexts.
Key Terminology
-
Russian archin
-
An obsolete Russian unit of length equal to approximately 0.7112 metres, historically used for measuring cloth and everyday lengths.
-
Bohr radius [b, a.u.]
-
The atomic unit of length representing the most probable electron-nucleus distance in a hydrogen atom's ground state, approximately 5.29177210903×10⁻¹¹ metres.
