Mondopoint is a footwear sizing system based on the foot length and linear width of the foot and is measured in millimetres. It is part of ISO standard 9407:2019, which describes the specification for Mondopoint system of sizing and marking. 1 It has the potential to replace various mutually incompatible shoe sizing systems used in different countries. Most of these systems use arbitrary numbers that do not relate to anything obvious. Even worse, different sizing systems are often used for men, women and children.

Official thinking on dual unit road signs in the 1960’s
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.

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.

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?

Did you know that there are purely metric signs (without any imperial conversions) on major roads at one hundred metre intervals? If you know this, you are one of the few who do. I am referring to marker posts and driver location signs. These signs are used by the emergency services to help them to locate stranded drivers and are incompatible with the official traffic signs for the general public, which are almost exclusively imperial.

A British driver in France has been stripped of his driver licence after misreading a 125 km/h speed limit sign for 125 mph. 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.

Dual units have been mandatory on restriction signs since TSRGD 2016. For height restrictions, the imperial and metric units normally appear on a single sign though they can appear on separate adjacent signs. Most height restriction traffic signs for bridges now show dual units. If your vehicle complies with both values, you can drive under the bridge. If your vehicle does not comply with either value, you cannot drive under the bridge. But what if your vehicle complies with only one of the values? Can you drive under the bridge in this case?

The Government have confirmed that there will be no more official publicity of driver location signs in a response to UKMA member Martin Vlietstra. Driver location signs use yellow font colour on a blue background with a white border and appear along the edges of motorways and on certain dual carriageway A-roads in England. They are normally spaced at 500 metre intervals.
