National Metrology Institute

Providing the UK's measurement capability

 

Metrology is the science of measurement. As the UK's National Metrology Institute (NMI), NPL's mission is to provide the measurement capability that underpins the UK's prosperity and quality of life. We are able to provide confidence in measurement results and data traceable to SI units.

Since 1900 we have developed and maintained the nation's primary measurement standards. These standards help provide confidence that the goods and services we buy live up to their claims, that the medicines we take are the right dosage, and the data we use for everything from climate change to financial trading is accurate. Our work also supports international trade and innovation in the commercial world.

UK measurement standards are underpinned by the National Measurement System (NMS), an infrastructure that ensures accuracy and consistency of measurement throughout the UK. We also represent the nation when liaising with international metrology and standards organisations and NMIs from other countries. We have over a century of experience meeting the requirements of the international measurement community.

Excellent measurement science

NPL led the review of the UK's national measurement capability in 2017. It looked at the UK's measurement infrastructure and how measurement knowledge can give industry a competitive advantage. The results are published in the UK Measurement Strategy and The Value of Measurement: Supporting Information forthe UK Measurement Strategy.

Measurement is everywhere, playing a vital role in our lives

The National Measurement System (NMS) is responsible for stimulating good measurement practice and enables UK businesses to make accurate and traceable measurements, for the benefit of the nation. The NMS is a network of laboratories that provide measurement standards and calibration testing facilities. It maintains the measurement infrastructure, represents the position of UK measurement internationally and influences the development of standards.

The NMS is funded by the Department for Business, Energy & Industrial Strategy (BEIS) and supports innovation in business by demonstrating the compliance of new products and processes, reducing development times and improving existing products. It disseminates measurement knowledge and information to the wider measurement community through events, research, case studies, training, newsletters, advice and guides.
