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.

The 1824 Weights and Measures Act introduced imperial standards based on physical objects with certain characteristics, such as the Imperial Standard Yard, and a single set of volume measures based on the new Imperial Gallon for dry and liquid measures to replace several that were in existence. To mark 200 years since the passing of the 1824 Weights and Measures Act, I look at the main features of the Act and ask whether it was a help or a hindrance on the path to metrication in the UK.

Twenty years have passed since the UK Metric Association published “A Very British Mess” (VBM). To mark the twentieth anniversary of the publication of VBM, I look at what has changed since its publication in 2004.

When a retailer weighs out his product in front of the customer, can the customer trust the scales? It is usually up to local government to certify the accuracy of such scales, though in recent years, certification of measuring devices within much of the world has been privatised with various countries’ national laboratories overseeing the certification process.

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.

Why are inches used in legislation and guidance on offensive weapons?
The Criminal Justice Act 1988 (Offensive Weapons) (Amendment, Surrender and Compensation) Order 2024 is a Statutory Instrument that was made on 30 April 2024 to tackle knife crime. Parts 1 and 3 of it came into force on 26 June 2024, Part 4 came into force on 26 August 2024 and Part 2 will come into force on 24 September 2024. Part 2 contains two references to measurement. One refers to the length of a weapon’s blade and the other refers to the distance of the serrated cutting edge from a blade’s handle. And they are both in inches.

SPOILER ALERT:
The official UK and USA metrology websites are INACCURATE
Since the inception of the International System of Units (SI) in 1960, it has always been recognised that some non-SI units, such as the litre, minute and hour, are “widely used and are expected to continue to be used for many years”.

Early Metrication on Southern African Railways
During the last decade of the nineteenth century, events in Southern Africa were dominated by the gold rush as adventurers scrambled to exploit the newly discovered in the Johannesburg area. This and the egos of and animosity between the financier and Cape Colony prime minister Cecil John Rhodes and the aging and dour president of the Transvaal Republic Paul Kruger resulted in the Anglo-Boer War of 1899-1902.

If like me, you are a fan of the Olympic Games, over the last 16 days you have probably enjoyed seeing the metric system used almost exclusively in TV coverage of the Games. It seems that the tendency, all too common in the 1970s, for British TV commentators to convert heights jumped, and distances thrown, into feet and inches, is definitely a thing of the past.
However, whilst most of the events, such as athletics, swimming and cycling, could be said to be exclusively metric, a few events still made use of non-metric measurement units.
Now that the Paris 2024 Olympic Games have come to a close, we take a look at some of the last hold-outs of non-metric units.

Iceland supermarkets lead the way for litre-based sizes of own-brand milk
So far, Iceland seems to be the only major British supermarket that is selling own-brand milk and all other milk brands in litre-based sizes. Why haven’t any other major supermarkets followed suit by dropping pint-based milk sizes?
