What is metrology?


From the Greek word “metron” = measurement. It is the science of measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology. (Source: International Bureau of Weights and Measures)

Why is metrology important?


Correct measurements are of vital importance to us all. As consumers, we need to know that we are getting our money’s worth every time we buy a kilo of rice or fish or a liter of gasoline. When we consult a doctor, we need to have faith in his or her ability to make an accurate diagnosis. Reliable measurements are critical in both situations.
We all depend on “an intricate network of services, suppliers, and communications that rely on metrology for their efficient operation,” states the Bureau of Weights and Measures.

Here are some examples:
  • Satellite navigation systems and international time correlation make accurate location possible—allowing the networking of computer systems around the world, and permitting aircraft to land in poor visibility
  • The economic success of nations depends upon the ability to manufacture and trade precisely made and tested products and components
