Taking measurements is one of the most common tasks we come across in our day-to-day life.Be it cooking, where measured amount of ingredients are added in order to cook food properly; purchasing items and artifacts, so that fixed amount can be allocated to certain object or quantity; in medicines, where a fixed dosage is required to treat a particular disease; sports, so as to decide the winner among the participants etc. Today, we follow standard unit of measurements for volume, mass, length and time. But ever wondered how these measurements were taken when such units were not introduced.
Historically, human body was used to provide the basis for units of length
A foot comprises 12 inches and three feet comprise a yard. With measurements such as these, it was easy to explain how far the next village was and to find out whether an object will get through a doorway.
These measurements also helped the people exchanges clothes and wood in a barter system.
