To become one of the leading national legal metrology agencies IN THE WORLD and contributing to the realisation of the objectives of the programme of the Federal Government of Nigeria.

The traditional system of Weights and Measures was applied in trade transactions before the introduction of colonial rule in Nigeria. However, in 1917, the traditional system of weights and measures was replaced by the Imperial System of Measurement by an ordinance promulgated by the then Governor General, Lord Lugard. The Ordinance gave the power of enforcing weights and measures laws to the Nigeria Police Force. The Police THOUGH were  overwhelmed by the responsibilities of enforcing weights and measures laws due to the increasing security challenges in the country.
 in 1960, the Federal Government established the Weights & Measures Division in the then Federal Ministry of Commerce & Industry in accordance with one of the recommendations of the Commission set up to probe the export of short weight graded cocoa bean.
The then Division of Weights and Measures WAS UPGRADED TO the Department of Weights and Measures in 2010 following the approval of the Federal Executive Council, and the subsequent appointment of a director.


Weights and Measures administration in Nigeria derives its power(s) from certain laws (Acts) and regulations.

Legal metrology is concerned with measurements where these influence the transparency of economic transactions, particularly where there is a requirement for legal verification of the measuring instrument. The Department of Weights and Measures enforces all legal metrology laws in Nigeria by virtue of the fact that the law confers on it the custody of Primary Standards of Measurement.
 Metrology in Everyday life:
•    The wealth of nations depends upon the ability to manufacture and trade precisely made and tested products and components.
•    Trade between countries often involve huge amounts of money, therefore a small error in measurement of, for example, flow rates and quantities of oil and gas can represent a significant amount of money.
•    Economic globalisation often requires that individual parts of complex engineered structures are manufactured in different countries. Metrology ensures that these parts fit together when the final system is assembled.
•    Human health depends on our ability to make accurate diagnoses requiring measurements, for example determining the level of cholesterol in blood.
•    Breath analysers are used to measure alcohol levels in the body.
•    Consumers need to trust the volume delivered by a petrol pump.


 The main activity of Weights and Measures Administration centres on the verification of the accuracy of weighing and measuring instruments used in trade and business transactions to promote consumer confidence and protection from unwholesome acts.
