Prince Albert and the measurement muddle in the 1860s

165 years ago, in his opening address at the London meeting of the International Statistical Congress, held on 16 July 1860, Prince Albert drew attention to the measurement muddle prevalent at the time, and was in no doubt that the muddle would have to go.

Words from his speech were included in the 1862 Report From The Select Committee On Weights And Measures, dated 15 July 1862.

Lib Dems block ability of Minister to allow metric measures for draught beer

The Liberal Democrats have become the latest political party to join the populist “save the pint” bandwagon. However, on this occasion their action will not only preserve the use of the imperial pint as the only legal measurement unit for the dispensing of draught beer, but arguably it will also prevent government Ministers from allowing metric measures for draught beer in the future, even if only as an optional alternative to pints.

Could metrication have shortened World War I by 2 years, and saved millions of lives?

In a follow up to an article last year, about the occasion in 1904 when Parliament came close to fully-adopting the metric system, we consider one of the possible consequences of this failure.

The health benefits of switching to metric beer sizes

This week saw the publication of research into the effects of reducing the standard serving size of draught beer in the UK.

The University of Cambridge study was described by its leader as being “the first real-world study to look at this”. It shows that reducing the current standard beer glass size in bars, pubs and restaurants from the current pint (568 ml) size has the potential to reduce the total amount of alcohol consumed in the UK, and should be given consideration as part of the Government’s fight to reduce the effects of alcohol consumption on health.

50 years of metric road signs in Australia

1 July 2024 marks the 50th anniversary of the switch to metric road signs in Australia.

For about a year before the change, car manufacturers fitted dual speedometers to their vehicles and, after 1974 all new cars were fitted with metric-only speedometers. Several kinds of speedometer conversion kits were available. As a result of all these changes, conversion on the roads occurred without incident.

Do our motorway junction numbers hinder the use of driver location signs?

Recent Metric Views articles have discussed the poor awareness of the meaning of driver location signs amongst the general public, and argued that despite their inclusion in recent editions of the Highway Code, there is still a need for a new public information campaign about these signs.

However, could there be another reason why driver location signs are poorly understood? And is there a solution that would both increase public awareness and increase their use?

How did campaigners for the metric system get their message across 120 years ago?

120 years ago, in addition to the activities of their members, the Decimal Association made use of pamphlets to make their case for the adoption of the metric system in place of the bewildering array of imperial weights and measures that were in use at the time.

House of Lords votes in favour of full adoption of the metric system

With the Queen’s Diamond Jubilee still fresh in people’s memories, and with a new King on the throne, it is a momentous time in our country’s history as the House of Lords votes unanimously to switch to the sole use of the metric system for all official purposes within a 2-year period.

The vote was undoubtedly influenced by the massive public support recently expressed in favour of the metric system.

Why the Government scrapped plans to convert UK speed limit signs to km/h in 1970

On 9 December 1970, the Minister for Transport Industries John Peyton announced that the Government have decided that speed limits will not be made metric in 1973 and have no alternative date in mind. Why did the Government scrap the metrication of speed limits? Historical government documents give various reasons for scrapping the planned conversion. This article will show some of these documents, which reveal the reasons the Government gave for its decision.

Government cost estimates to convert all UK speed limit signs to km/h in 1970 were far below £30 million in today’s money

The British Government once developed and examined proposals to change all UK speed limit signs from miles per hour to kilometres per hour in the 1960’s and in 1970. On 9 December 1970, the Minister for Transport Industries John Peyton announced that the proposed metrication of speed limit signs would not go ahead and was postponed indefinitely. The proposed change to metric speed limits was due to be implemented in 1973. Fifty years have now passed since then. Half a century later, UK speed limit signs are still in imperial units. The Department for Transport (DfT) now claims that metricating UK road signs costs too much. However, it would have cost little to convert all UK road signs to metric units according to cost estimates by the Department of the Environment (DoE), which had responsibility for transport at the time, according to historical government documents held at the National Archives.
