"Standards" of measurements have been in existence from the appearance of organized societies. For example, ancient Athens had its own central depository of official weights and measures and some of these survive today. Merchants were required to take their weights and linear and volume measures to the Tholos to compare them with the standard examples. Merchants caught short-changing their customers were subject to fines just as they are today.
