Objective of Measurement :
Measurement is the most important aspect of our life. We use measurement in science, engineering, business trading, personal life, education, and more other fields. As technology is growing day by day so we need a highly accurate and easy convenient global measuring system in each and every field. It is essential to use standard measurement in every field that everyone to be sure that they not get cheated.
History of Measurement:
In history for measurement people used the human body as a tool. For measuring length used forearm, hand, foot & finger as a unit. The foot, finger is a subdivided shorter unit of a length. This type of measurement is not accurate cause different in size of the arm & finger for different people & some of the countries still using it. In history, there were lots of measuring systems developed but mostly used imperial, the metric system of measurement. We use these systems for measure distances, volume, weight, speed, area etc. Due to this a major problem everyone is facing while doing trading between the countries. A huge improvement in civilization, It necessary to improve measuring standards. Nowadays International Standard (SI) units are used as a global measurement system.
Few 100 years back clock is not discovered so people use to measure time by Sunlight, Sand Clock & Sundials where used. The sand clock is a device which consists of two glass chambers. One chamber is filled up with sand, this sand will move from one chamber to other chambers in a dedicated time. Sundial is a device by this people know the time by the position of the sun. Sundial has a flat plate with gnomon ( It produce a shadow) attached to it. As the sun moves the gnomon is shows shadow in a different direction on the sundial plate by this people will know the time.
