The National Measurement Office (NMO) ensures the UK’s system of weights and measures is fair, accurate and legal so that consumers and businesses have confidence whenever they buy and sell by quantity. Each year in the UK, £622 billion worth of goods and utilities are sold on the basis of the measurement of their quantity.
