Measurement is the process of comparing unknown magnitude of certain parameter with the known predefined standard of that parameter. For the measurements results to be accurate, two conditions should be met.
Measurements are one of crucial parts of not only mechanical engineering but all types of engineering fields. Every branch of engineering involves two processes: design, and operations and maintenance. The design may be machine design, building design, circuit design, transportation design, automobile design etc. The operations part involves operation of the machines, automobiles, various plants, circuits etc.
