What is Metrology

Staff of the Metrology Department

Metrology is best described as the scientific study (including all theoretical and practical aspects) of measurement. This measurement is made by comparing an unknown quantity to a known standard by means of a consistent system of units. The system of units is known globally as the International System of Units (SI). For example, the kilogram is the unit for mass and the second is the unit for time. During this study, a quantity with a numerical value is obtained with some aspect of accuracy and precision. There are three (3) areas of Metrology namely Legal, Industrial and Scientific.
