📚A Brief History of Weight Measurements
The metric system, including the kilogram, was developed during the French Revolution to create a universal, decimal-based measurement system. The kilogram was originally defined as the mass of one liter of water at its maximum density.
The pound has ancient origins, deriving from the Roman 'libra' (hence the 'lb' abbreviation). Various pounds existed throughout history until standardization efforts in the 19th and 20th centuries established the international avoirdupois pound we use today.
👉 Today, while most of the world uses kilograms, pounds remain common in the US, making conversion tools essential for international communication and trade.
