Abstract

It is generally accepted that accurate measurement is essential to everyday life. However, the infrastructure that delivers the accurate measurements we all rely on goes almost unnoticed – not least because it operates so well. This Feature Article shines a light on the role of metrology – the science of measurement – in maintaining this infrastructure and the system of measurement units that underpins this, with a particular focus on the mole and on chemical measurement. The article also highlights the recent changes that have occurred to our measurement system and the way we define the mole and other units. This is perhaps the greatest story of scientific progress and international collaboration in recent times – with chemistry making key contributions in several areas – but a story that few have heard.
