Martin Vlietstra proposes a new British technical keyboard that includes non-breaking spaces and some common characters used for metric symbols. In his proposal, he considered various categories of user and using the restriction of inline Unicode characters, has proposed a keyboard that will not only handle all the characters needed by SI, but will also handle many of the characters needed for chemical formulae, and includes Greek characters such as ‘π’, ‘θ’ and other commonly used symbols from mathematics and physics including ‘×’, ‘÷’ and ‘±’. He uses the standard British keyboard as the basis for his proposal and explains how a lot of new characters can be supported using key combinations with the Alt Gr key. It covers a lot more than the extra characters for the correct display of metric symbols.

Government accepts CE mark indefinitely in nod to common standards
From the end of 2024, the British Government was planning to impose a requirement for goods to carry a new UK-only UK Conformity Assessed (UKCA) mark. Manufacturers who used to need only a conformité européenne (CE) mark for all European countries would have had to meet separate safety standards for the UKCA mark just for the UK and a CE mark for the rest of Europe. After opposition from industry, the Government has backed down and decided to allow the European Union’s CE mark for the UK market indefinitely in a nod to the need for common standards. Will the Government accept the same logic for the use of the common global measurement system known as SI, the modern metric system?

The BIPM’s SI brochure states “The numerical value always precedes the unit and a space is always used to separate the unit from the number.” and says that the space, not a comma or a dot, shall be used for the thousands separator. There are several space characters in computing, but the brochure does not state what kind of space you should use when typing. Ideally, you would use a non-breaking space to ensure that no line break separates the numerical value from the unit. Users face the same issue when using a space for the thousands separator.

All seven base units in the metric system are based on constants of nature. This means that they can never be destroyed. The seven SI base units are the metre, kilogram, second, ampere, kelvin, mole and candela. All other SI units are derived from these base units. Hence, they are called SI derived units. Anyone with the right laboratory equipment and expertise can reproduce any of these base units. The problem with tying units to physical objects is that they can be destroyed, and they tend to degrade over time.

On 4 April 2023, London City Airport scrapped the 100 ml liquid rule. 1 Since 2006, airports worldwide have insisted that travellers can only bring liquids in containers of up to 100 ml in their carry-on bag. 2 These days, we take it for granted that the 100 ml limit for liquids at international airports around the world is exactly the same quantity. This is a triumph for the metric system, which replaced many different national systems long ago. Before the metric system, the same unit names were used for different quantities in different national measurement systems and there was no common definition for these units. The worldwide 100 ml liquid rule shows the benefits of a world standard measurement system for international travellers (i.e., the metric system).

The Mayor of London Sadiq Khan has expressed his commitment to expand the Ultra Low Emission Zone (ULEZ) this year to make London’s air cleaner and improve public health. Transport for London (TfL) is planning to expand ULEZ across all London boroughs from 29 August 2023. As ULEZ expansion has been in the news recently, we take a look at the measurements that ULEZ is based on. Whatever happens to ULEZ, measurements play a central part in making it work. Unlike UK road signs, the measurements used in ULEZ are all metric.

The Chartered Trading Standards Institute (CTSI) established the Safeguarding our Standards (SOS) campaign in response to the Government’s proposed Retained EU Law Bill (REUL Bill). The Bill threatens food safety, product safety, animal health and welfare, fair trading, legal metrology and protection against scams and rogue traders. UKMA is concerned about the Bill’s threats to weights and measures legislation, which could undo many years of metrication progress. Last month, CTSI invited UKMA to join the Safeguarding our Standards coalition and UKMA agreed to join. SOS comprises a coalition of organisations and individuals with an interest in maintaining the protections that the people of the United Kingdom have benefited from for years.

A new Barbados Metrology Bill 2022 was recently introduced in the House of Assembly. Minister of Energy and Business Development Kerrie Symmonds has said that the failure of align Barbados’ metrology with international standards (i.e., failure to fully adopt the metric system) has incurred economic costs. Nation News reports that “Consumers could soon be getting protection from the state in regards to having measurement systems across the board that align with international standards.”.

With Brexit still dominating the news, Ronnie Cohen looks at one of the biggest obstacles to completing our transition to the metric system: its perceived link to the European Union.

Global Britain or Imperial isolation?
On 29 March, Sir Tim Barrow, Permanent Representative of the United Kingdom to the European Union, handed a signed six-page letter from the British Prime Minister to the President of the European Council, invoking Article 50 of the Lisbon Treaty and confirming the UK’s intention to leave the EU. So where do we go from here?
