What is a metrologist?

A metrologist is a person who studies weights and other such measurements.

A metrologist studies a variety of measurement systems such as those for speed, force, and size. A majority of metrology (the study of weights and measures) is establishing new technology, machinery, software, and scientific means of analysis for measuring data of all kinds, particularly those in the fields of electronic engineering and computer science. 

Metrologists can often be found assisting in architecture, engineering, and construction. The tools that they develop and their research can be used to measure physical structures for flaws as well as calibrate equipment and measure empirical data to provide feedback and planning advice.

The term metrologist is sometimes mistakenly used for meteorologist, a person who studies meteorology, the science of weather.

Example: The metrologist fine-tuned our equipment and said we should be good to start building as soon as the wind slows down.

Where does metrologist come from?

The first records of the term metrologist come from the 1840s. It combines the term metrology, meaning “the science of weights and measures” and the suffix -ist, which denotes a person who practices something. A metrologist practices the science of weights and measures.
