1. Introduction to Weighing Scales in Uganda)

A weighing scale is a device used to measure weight or mass. These are also known as mass scales, weight scales, mass balances and weight balances.

Weighing scales have been an essential part of human civilization for centuries. These devices, used to measure the weight or mass of objects, have evolved from simple mechanical tools to sophisticated digital systems. Their history dates back to ancient civilizations like Mesopotamia and Egypt, where balance scales were used for trade and commerce.

The earliest balance scales were simple beam balances, consisting of a horizontal bar suspended on a central pivot. Equal weights were placed on either side to measure objects. Over time, these scales became more sophisticated, incorporating counterweights and materials like brass and bronze for durability and accuracy.
