The word "metrology" is correct and well written in English
It is used in the context of the science of measurement, particularly in fields like engineering and manufacturing. Example: "The accuracy of the instruments used in metrology is crucial for ensuring quality control in production." Alternatives include "measurement science" or "science of measurement."
Its atoms come in three distinct isotopes (each with a different mass), and the ratios of the three isotopes in a crystal of silicon are still too uncertain for good metrology.
In April, a team from the European Commission's Institute for Reference Materials and Measurements, in Belgium, reported some progress on this front, but many metrologists wonder if the problem can ever be solved.Among the sceptics is Michael Gläser, who works at the German national metrology laboratory in Braunschweig.
This summer, however, three teams of researchers from the national metrology laboratories of Australia, Japan and Italy—joined forces to get as close as 400 atoms in a billion.
In the process, he shows that the story of metrology, not obvious material for a page-turner, can in the right hands make for a riveting read.In this section Punchline From yardsticks to metre rule The first cut is the deepest A terrible beginning The bold standard ReprintsThe earliest known units met the first two of Mr Crease's requirements well.

Completely separated from the Mediterranean-European history of metrology is that of ancient China; yet the Chinese system exhibits all the principal characteristics of the Western.
He participated in the compilation of the official histories of the Jin (265 420) and Sui (581 618) dynasties, writing the chapters containing historical outlines of Chinese astronomy, astrology, metrology, and a mathematical theory of music.
Dr Gläser's planned apparatus (designed in collaboration with Zhou Baoguo, of the National Institute of Metrology in Beijing) will create a beam of gold atoms that have been ionised (ie, stripped of an electron) to make them electrically charged.
His father is the chief executive and the principal owner of Dorsey Metrology International, a manufacturer of precision measuring instruments in Poughkeepsie.
However there are also many smaller schemes, including a £1m project to create the Silverstone Metrology Centre in Northamptonshire – a high-precision measurement facility for hi-tech businesses – and a a glass academy in Sheffield to train people to work in the city's glassworks.
Veeco Instruments of Plainview (Nasdaq VECOO) has set up an integrated Metrology Group and appointed Don Kania group president.
