55 years ago today, the Government announced that,
In the 55 years since that announcement, successive governments have failed to set a new date for the changeover to metric speed limits. We reproduce here an extract from UKMA’s main website:

How are speedometers designed to accommodate the change from mph to km/h? In this article I will examine a variety of techniques and at the end of the article I will propose a 21st Century solution.
Continue reading “Speedometers and Metrication”Today marks the 20th anniversary of the metrication of speed limits in the Republic of Ireland. 20 January 2005 was the day that all speed limits in Ireland switched from mph to km/h.

HM Government looked at the case for and against the use of dual unit road signs as an intermediate step in the metrication of road signs in the second half of the 1960’s. Three different methods for dual unit sign conversion were evaluated and some technical issues related to dual unit signs were discussed. The findings and illustrations from the National Archive papers are presented here.

This is not the first time that miles and kilometres have been confused when reading speed limits. Back in January 2021, Metric Views reported a similar case of a high-profile foreign Premier League footballer who confused km/h and mph when driving in the UK. And it is unlikely to be the last time it happens.

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.
Continue reading “Why the Government scrapped plans to convert UK speed limit signs to km/h in 1970”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.
Continue reading “Government cost estimates to convert all UK speed limit signs to km/h in 1970 were far below £30 million in today’s money”Last month, there were reports about vigilantes damaging ULEZ cameras in London and 20 mph speed limit signs in Wales. These incidents were widely reported in the British media. By contrast, the media ignore a group of imperial vigilantes who take the law into their own hands and deface, damage and remove metric signs. They also ignore market traders and small shops that price loose goods by the pound only (with no metric equivalent) in defiance of the Price Marking Order. Why are the authorities intimidated by them?
Continue reading “Why are the authorities afraid to tackle law breaking by imperialists?”The total estimated cost for implementing the speed limit change from 30 mph to 20 mph, including the cost for changing signs and markings on roads, has been published in the Regulatory Impact Assessment (RIA) undertaken by the Welsh Government on 20 mph speed limits. The published document gives a breakdown of road sign costs. These costs are several times lower than the Department for Transport (DfT) cost estimates of conversion of road traffic signs to metric units in cash terms despite 50% inflation during the 16-year period between the two reports.
Continue reading “Welsh road signs in 2022 cost small fraction of DfT estimates in cash terms despite 50% inflation since 2006 DfT metric conversion report”For years, the DfT has given cost and diversion of funds from other parts of the transport budget as arguments against the metrication of UK road signs. While all kinds of arguments have been made for and against the reduction of the speed limit on local roads to 20 mph in London and Wales, I have not heard any opponents of the rollout of 20 mph speed limits say that it costs too much or that it diverts funds from other parts of the transport budget. This shows that the DfT arguments against changing road signs to metric units are bogus.
