Happy World Metrology Day!
The measurement science community is celebrating World Metrology Day on 20 May 2019.
This year the event is dedicated to 'The International System of Units - Fundamentally Better'.
In November 2018 the General Conference on Weights and Measures took a historic vote to make the SI units entirely determined by constants of nature.
On this year's World Metrology Day that vote - and the decades of hard work that contributed to it - become reality. read more >>
UNIT OF THE MONTH: The kilogram
Accompanying the redefinition of the International System of Units (SI), on the 20th of each month we have been looking at one of the seven SI base units since November 2018.
You'll be able to find out where the units are used in everyday life, how they have been defined, and the changes that came into force on 20 May 2019.
Discover the SI unit of the month (20 May to 19 June), the last unit we’ll be looking at, the kilogram >>

The ocean is a key component in the global climate system. It is a sink for carbon dioxide and increasing ocean temperatures lead to rising sea-levels. The characterisation of the status of the oceans and their circulation requires world-wide monitoring of a wide variety of ...
Earth observation agencies worldwide are moving towards a more coordinated approach to data gathering. With the increased importance of the data they provide, they are demanding improved measurement accuracy of the instrumentation on board Earth observation satellites. Satel...
