Weights and Measures Acts (UK)

There have been many laws concerned with weights and measures in the United Kingdom or parts of it over the last 1,000 or so years. The acts may catalogue lawful weights and measures, prescribe the mechanism for inspection and enforcement of the use of such weights and measures and may set out circumstances under which they may be amended. Modern legislation may, in addition to specific requirements, set out circumstances under which the incumbent minister may amend the legislation by means of statutory instruments. Prior to the Weights and Measures Act 1985, weights and measures acts were only concerned with trade law where the weight or size of the goods being traded was important. The 1985 act, however, had a broader scope, encompassing all aspects covered by the European Economic Community (EEC) European Commission directive 80/181/EEC. , the current primary legislation in the United Kingdom is the 1985 act, which was last amended by statutory instrument in 2011. Statutory instruments made under the authority of the act do not amend the act '''', but regulate particular areas covered by the act. The act is currently enforced by the 200 Trading Standards offices managed by local authorities around the country. Definitions of units of measurements and the technical equipment relating to weights and measures are provided by the National Measurement Office, an agency of the Department for Business, Innovation and Skills. Statute measure Historically, many units had various customary definitions—by locality or trade, for example. Where these units also had a standard, legally defined definition, such as given in a weights and measures act, this was known as the statute measure. So a land area might be given as 24 acres—statute measure, to clarify that it was the acre defined in statute, rather than a customary acre of a different size, that was being used. ==Metric units of measure==

The Weights and Measures (Metric System) Act 1897 (60 & 61 Vict. c. 46) provided that metric units could be used in addition to the traditional imperial units for purposes of trade. In practice, the actual choice of units was restricted by price marking orders which listed packaging sizes and pricing structures that might be used in specific circumstances. For example, as of April 2012, wine for consumption on premises may only be sold in 125, 175, and 250 mL glasses while draught beer may only be sold as , , or pint and integer multiples of pint. Prior to 1973, when the United Kingdom joined the EEC, such specifications were almost all in imperial units. As part of its attempt to harmonise units of measure between the member states of its Internal Market, the European Commission (EC) issued directive 80/181/EEC which set out the units of measure that should be used for what it called "economic, public health, public safety, and administrative" purposes. To comply with this directive, the Weights and Measures Act 1985 extended the scope of Trading Standards responsibilities from just matters related to trade to all aspects of the directive. For example, it was the Trading Standards Office that criticised the use of sub-standard weighing machines in NHS hospitals. To help ease the EC's desired transition from sole use of imperial units to sole use of metric units, the directive permitted the use of what were termed "supplementary indicators"—the continued use of imperial units alongside the metric units catalogued by the directive (dual labelling). The initial intention was to prohibit dual labelling after the end of 1989, with metric units only being allowed after that date. This deadline was later extended: first to the end of 1999, then to the end of 2009. Finally, in 2007, the European Union (EU, as it had become) and the EC confirmed that the UK would be permitted to continue indefinitely to use imperial units such as pints, miles, pounds and ounces as at present. The Gloucestershire County Council Trading Standards Department confirmed the EU ruling that the previous deadline for ending dual labelling had been abolished. There are still a few cases where imperial units are required to be used and where metric units are not permitted within the scope of the Weights and Measures Act, such as the pint for the sale of draught beer and cider, and miles and yards for distances on road signage. Milk in returnable containers may be sold by the pint and the troy ounce may be used for the sale of precious metals. In addition, British law specifies which non-metric units may be used with dual labelling (for example the imperial gallon, but not the US gallon). ==England==

Acts of the Witenagemot Numerous acts of the Saxon kings are known to have been lost. Those that have survived include: 10th century 2 Edgar c. 8 (sometime between 959 and 963): The statute also survives in a few other Old English and Latin copies, some which omit mention of London and describe "the measure held at Winchester", an indication that a standard ell or yard was nominally in use: John Quincy Adams's 1821 report on the history of English weights and measures notes of this act that "it was never observed".
