In Jainism, "Ek Arya Desh" (एक आर्य देश) is a term found in ancient texts and refers to a specific measurement used in Jain cosmology (Lokavijñāna). "Desh" means "country" or "region," and "Ek Arya" refers to a unit of measurement, commonly used in descriptions of Jambudvipa and other cosmic regions.

• Ek Arya is a unit of length, often used to describe distances in Jain cosmological diagrams (like the dimensions of Jambudvipa, Bharata Kshetra, etc.).
• K in your question is unclear, but if you are asking "Ek Arya Desh from K," it could be interpreted as asking "What is the measurement of one Arya Desh in terms of K?"

In Jain cosmology, the units of measurement progress as follows:

• Angula (fingerbreadth)
• Dhanusha (bow-length)
• Gavyuti
• Yojana
• Rajju

"Arya" and "Desh" sometimes refer to sub-divisions of these, but the exact correspondence can vary based on the text.

Example from Jain texts:

• 1 Yojana = 4 Krosa (Kos)
• 1 Krosa = 2000 Dhanusha
• 1 Dhanusha = 4 cubits (hasta)
• 1 Arya = 1000 Dhanusha

However, these numbers can vary, and "Ek Arya Desh" is often used more as a conceptual or regional unit rather than a strict linear measurement.

If you have a specific Jain scripture or context in which "Ek Arya Desh" is used, please provide it for a more precise answer.
