The metre used with the appropriate prefix is capable of measuring vast distances across the universe and the tiniest particles in the universe. These prefixes remove the need to use enormous numbers with lots of trailing zeroes. So why do astronomers continue to use astronomical units (AU), light years and parsecs? These non-standard units can be replaced by the metric unit of length, the metre, with the appropriate prefix.

Gibraltar is far ahead of UK on metric road signs
I came back from a short trip to Gibraltar one week ago and noticed that all their road signs were metric. The only imperial units I saw on road signs there were on dual-unit restriction signs.

On 4 April 2023, YouGov carried out a survey of 4808 British adults about changing the rules around speed and distance in the UK from miles to kilometres. It revealed insights on different attributes based on region, politics, and age.

Some aspects of measurement usage in the British transport sector appear to be uniquely British with no known parallel across the whole world. The British really are out of step with the modern world when it comes to transport measurements. The British transport sector is one of the last imperial bastions in the UK thanks to DfT policies.

A recent visitor to UKMA’s web site has made contact with us explaining that, when clearing out a loft, she had discovered what appeared to be proposals for a “Think metric” campaign aimed at the general public. She says, “It would be interesting to know if they were used or not and where”.

I recently came across a news article on the mylondon.news website reporting that one short London Underground journey is the most expensive in the world.

Now that we have all become accustomed to metric social distance signs, it might be a good time to look at their legality, which some have questioned. Ronnie Cohen has investigated and reports his conclusions.

Following on from his article about social distancing in the UK (Metric Views, 16 April), Ronnie Cohen now considers the contribution of the global measurement system to understanding the pandemic.

No flight information please – we’re British
Ronnie Cohen wonders why at least one budget airline flying from the UK targets its flight information at continental and American passengers.

British drivers face a continuing sign muddle
With the end in prospect for road traffic signs showing imperial-only vehicle dimensions, Ronnie Cohen takes a look at the current muddle.
