The effects of the science of measurement are seen everywhere,allowing people to plan their lives and make commercial exchanges with confidence.For example,most people assume that the clocks in their homes and the clocks in their workplaces all display approximately the same time.A pound of hamburger purchased at one grocery store will contain the same quantity of food as the same amount purchased at a store across town.Also,a screw purchased from Company A will fit into a hole made by a drill purchased from Company B,assuming they are specified to the same size.
The basic principles of metrology are simple.Metrology involves measurements and comparisons of a measurement standard to either another measurement standard or to a device of unknown accuracy.It involves the design of tests and methods by which the measurements and comparisons are made,and analysis of the results of the tests.The ultimate references for all measurement quantities(length,current,time,etc.)have been agreed on by international treaties.
