Metrology is the Science of Measurement. It includes theoretical & practical problems, the realization of the units of measurement and their physical representation as well as measuring instruments & their field of application. Legal Metrology is the name given to all applied metrology subjected to regulations by law or government decree.

The extent of legal metrology varies from one country to another. In most countries legal metrology covers measurements in the protection of the individual from financial, health & environmental point of view.

According to international practices, legal metrology has application in three broad fields, namely, commercial transactions, measurements needed for ensuring public health and human safety and industrial measurements.

Legal Metrology” means that part of metrology which treats units of weighment and measurement, methods of weighment and measurement and weighing and measuring

instruments, in relation to the mandatory technical and legal requirements which have the object of ensuring public guarantee from the point of view of security and accuracy of the weighments and measurements. (Section 2(g) of Legal Metrology Act, 2009)

The Legal Metrology Act, 2009 (Act 1 of 2010) repeals and replaces the Standard of Weights and Measures Act, 1976 and the Standards of weights and Measures (Enforcement) Act, 1985. The central government has appointed the date 01.04.2011 from which the provisions of the Act will come into force.


1. Department of Consumer Affairs under Ministry of Consumer Affairs, Food and Public Distribution

The Department of Consumer Affairs under Ministry of Consumer Affairs, Food & Public Distribution is responsible for the formulation of policies for Monitoring Prices, availability of essential commodities, Consumer Movement in the country and Controlling of statutory bodies like Bureau of Indian Standards (BIS) and Weights and Measures.

The weights and Measures Unit in the Department of Consumer Affairs, is the central authority for dealing with the subject and is required to handle all matters falling within the purview of the Central Government. In addition, it has to guide, co-ordinate and supervise the enforcement activities of the state enforcement machinery.

The responsibility in relation to weights and measures is shared between the Centre and the States. Matters of national policy and other related functions such as, uniform laws on weights and measures, technical regulations, training, precision laboratory facilities and implementation of the International Recommendation are the concern of the Central Government. The State Governments and Union Territory Administration are responsible for the day to day enforcement of the laws.

2. Directorate Of Legal Metrology

Enforcement of Standards and Weights and Measures Act is entrusted with the Directorate of Legal Metrology in each state which is essentially a 3-tier Organisation comprising Inspectors of legal Metrology at the field level, Assistant Controller of Legal Metrology at the district level and Controller of Legal Metrology with four Deputy Controllers sitting at the State Level. Legal standards of weights and measures of the States and Union Territories are calibrated in the four Regional Reference Standard Laboratories (RRSL) located at Ahmedabad, Bhubaneswar, Bangalore and Faridabad. These laboratories also provide calibration services to the industries in their respective regions. They are among the recognised laboratories for conducting the model approval tests on weights and measuring instruments.


The organization of Weights & Measures was established in 1958 with the object of bringing about the uniformity in Weights & Measures in accordance with the international standards so as to facilitate trade and commerce.

The Standards of Weights and Measures Act, 1976 providing for establishing Standards of Weights and Measures, regulation of inter-State trade or commerce in weights and measures and other goods which are sold by weight, measure or number was enacted in 1976. In the year 1985, the Standards of Weights and Measures (Enforcement) Act, 1985 was enacted for enforcement of standards of weights and measures established by or under the 1976 Act.

Ever since in view of rapid advancement of science & technology and globalization of economies, there has been vast improvement in weighing and measuring techniques and has extended the scope of weights & measures. With the view to establish the standards of Weights & Measures, regulate trade and commerce in Weights & Measures and other goods which are sold or distributed by weight, measure or number and for matter connected therewith or incidental thereto, the Legal Metrology Act, 2009 was enforced on 1-4-2011.
