Weights in Harappan Civilization

The Harappan civilization is renowned for its sophisticated urban planning and trading systems, which included a precise system of weights essential for regulating exchanges. These weights were primarily constructed from a type of stone known as chert, usually taking a cubical shape with no markings. The standardization of weights was meticulous, encompassing both binary and decimal systems. The binary weights ranged from 1 to 32, while higher denominations followed a decimal system up to 640. Smaller weights were likely used predominantly for measuring items like jewelry and beads. Additionally, evidence suggests the existence of metal scale-pans, indicating a structured approach to trade and measurement during the civilization's height.

Exchanges were regulated by a precise system of weights, usually made of a stone called chert and generally cubical, with no markings. The lower denominations of weights were binary (1, 2, 4, 8, 16, 32), while the higher denominations followed the decimal system (160, 200, 320, 640). The smaller weights were probably used for weighing jewellery and beads. Metal scale-pans have also been found.

Detailed Explanation

The Harappan civilization had a well-defined system of weights that was crucial for trade. They used cubical weights made from a type of stone called chert. These weights did not have any markings, which meant that their weight was standardized. For instance, lower weights were organized in binary form, doubling with each increment (1, 2, 4, 8, 16, 32), whereas higher weights utilized a decimal system that started from 160 and increased by hundreds up to 640. Smaller weights were likely used for light items, such as jewelry and beads, indicating the civilization's advanced level of commerce. Additionally, metal scale-pans discovered at sites suggest a system that not only weighed but also measured goods accurately.

Examples & Analogies

Imagine going to a grocery store today where scales are used to weigh produce like fruits or vegetables. Just like modern-day shops use standardized weight systems to ensure everyone gets the right amount, Harappan merchants used these weights to avoid cheating during trade, ensuring fairness in their bustling markets.
