national metrology institutes

National metrology institutes (NMIs) are organizations within a country responsible for establishing and maintaining measurement standards to ensure accuracy and consistency. They develop and verify measurement tools and procedures for scientific, industrial, and everyday use. NMIs ensure that measurements, such as those for weights, temperature, or electrical data, are uniform across industries and borders. This helps in trade, safety, and technological innovation. They often collaborate internationally to harmonize measurement standards, supporting global compatibility and trustworthiness in scientific and commercial activities.
