An old Russian unit of length, approximately equal to 28 inches or 71 centimeters.
From Russian 'аршин' (arshin), possibly from Persian 'arsh' (height) or related to an elbow-cubit measurement. The term traveled through trade routes to measure cloth and land.
Before metric systems, different countries had wildly different measurements—Russian merchants used the archine to trade, and you had to know dozens of these local measurements just to do business!
