Standardized Weights
The Harappan civilization is renowned for its use of standardized weights, which were crucial for trade. These weights were typically made of stone, particularly chert, and came in various shapes, such as cubes and cylindrical forms.

• Weights were meticulously crafted to ensure uniformity, facilitating fair trade practices.
• The use of a standardized weight system indicates a developed economy and organized trade networks.

Measurement Units
The Harappans employed a sophisticated system of measurement that was likely based on the decimal system. This system included units for length, weight, and volume, which were essential for various trade and agricultural activities.

• They used a specific ratio, where the smallest unit was a "digit" (approximately 1.77 cm).
• This advanced measurement system suggests a high level of mathematical knowledge and practical application.

Trade Practices
The weights and measures in Harappa played a pivotal role in trade both locally and with distant regions. The uniformity in measurements allowed for smoother transactions and increased the trust between traders.

• Trade artifacts found in Harappan sites indicate that goods were exchanged with other civilizations, such as Mesopotamia.
• The precision in weights enabled the Harappans to engage in complex trade networks that contributed to their economic prosperity.

In summary, the Harappan civilization showcased advanced features in weights and measures, which were essential for their trade and economic systems. The use of standardized weights, a well-defined measurement system, and effective trade practices highlight their sophistication in commerce.
