Animals measure distances and weight for their survival. On the other hand, stemming from their need to communicate to live in society, humans created languages and, later, established the standards of measuring. Whether for moving around, portioning food, making tools, or calculating the weight of objects and animals, measurement standards arise from this need that was already present in human activities in the age of chipped stone and has been with us ever since. Nowadays, most of the world's population uses meters and centimeters to measure distances. These standards come from the need to establish comparisons that allow trade between peoples and also from political and social disputes.
