Metrology File

In our daily life we are constantly confronted by measurements without being aware of them as such. It appears to be obvious that all measurements are comparable and unified. The enclosed book shows us that this was not always the case.

To be precise, «metrology» is the general term used for the science of measurement and applies not only to the capture of length, but also of time, temperature, mass or any other physical measurement. This booklet focuses on dimensional metrology providing the reader with the historical background of the field.

The first chapter of the e-book describes the long and winding road of the unit of length – the metre – from the date of its birth until the time it was granted its legal recognition as a universal standard unit. The second chapter will reveal the existing history and importance of gauge blocks and the way they are calibrated. The third chapter will finally give an overview of common definitions and published standards used in dimensional metrology.

Knowledge of the history generally helps us to develop a better understanding of the presence in science and technology.

The basics have become all the more important as the growth of technology bring with it the need for higher precision and accuracy. In the age of global markets and decentralised production, highly accurate measures are one of the most important requirements for assuring the quality of industrial products The “Metrology File” will lead you on voyage of discovery through the milestones that have marked the history of metrology.
