Measurement is a way of keeping track of the size, shape, or amount of something. Measurement has been part of our lives since the early days of civilization. People in ancient times developed a variety of tools and methods to measure things. They used ropes and sticks to measure distances and objects. They also used stones and pebbles to measure the weight of things, and used the shadows of the sun or stars to tell the time. Different cultures developed different ways of measuring things. Over time, people created more precise and accurate ways to measure things. Today, we use rulers, tape measures, scales, and other types of measuring tools to get exact measurements of objects.
