European Metrology

Metrology, the science of measurement, is one of the oldest sciences going back as far as recorded history. From rudimentary measurements that supported early, geographically isolated communities, to technological developments and scientific advancements in today’s world; measurements underpin everything around us. Our transportation systems, the heating in our homes or offices, and the food we consume, all depend on metrological infrastructures that pervade all levels of human activity. Even worldwide trade is only possible because of the principle of a common, standardised system of measurements. Through the work of metrological organisations, like EURAMET and WELMEC, we now rely on an International System of Units (SI) – for which the basis was laid with the Meter Convention in 1875 - to enforce globally consistent measurements for international trade and scientific accuracy. Today, the SI continues to evolve, with its base units last undergoing a major redefinition in 2019 to ensure the system’s suitability for our 21st century world.
