BURMA HARDWARES

The history of Legal Metrology—the branch of metrology that treats units of measurement, methods of measurement, and measuring instruments in relation to mandatory technical and legal requirements—is as old as human civilization itself. It evolved from a basic societal need: ensuring honesty, equity, and trust in trade.
​Here is a chronological journey of how weights and measures transformed from regional, body-part-based systems into a unified global legal framework.
​1. Ancient Civilizations: The Birth of Standards (Pre-3000 BCE – 500 BCE)
​In early societies, trade relied heavily on barter, which quickly necessitated standard measures to prevent conflict. The earliest standards were based on nature or the human body.
​The Indus Valley Civilization (c. 3000–1500 BCE): One of the most sophisticated early systems. They achieved remarkable accuracy using standardized flint weights in a binary and decimal system (ratios of 1, 2, 4, 8, 16, 32, 64, etc.).
​Ancient Egypt: The Royal Cubit was established based on the length of the Pharaoh’s forearm plus the width of his palm. To ensure accuracy, the granite master standard was maintained by royal architects, and workers had to recalibrate their wooden cubit sticks every full moon under penalty of death—an early form of legal metrology enforcement.
​Babylonia & Mesopotamia: King Hammurabi’s famous code included laws governing weights and measures, punishing merchants who used fraudulent scales.
​2. Greco-Roman and Medieval Eras: Royal Supervision (500 BCE – 1500 CE)
​As empires grew, the centralization of measurement laws became a tool for tax collection and economic stability.
​The Roman Empire: The Romans standardized the Libra (weight) and Pes (foot). Standard models were kept in the Temple of Castor and Pollux in Rome. They introduced the concept of inspecting market weights, a duty assigned to officials called Aediles.
​The Magna Carta (1215 CE): In England, King John signed the Magna Carta, which explicitly stated the need for uniform weights and measures across the realm to protect buyers:
​"There shall be standard measures of wine, ale, and corn... and it shall be with weig
