Metric Views looks at a successful but unsung project that took place during the early years of the UK’s metric transition. We speculate what might have occurred had this job been the responsibility, not of local government, but of the UK Department for Transport (DfT), and we draw attention to a paradox.

US customary measures: friend or foe of British traditionalists?
In the early years of the twentieth century, both US customary (USC) and metric measures were seen by some in Britain as threats to the survival of the Imperial system. The end of Empire saw metric supplant Imperial, while USC has endured. Could it become the saviour of the few Imperial measures that survive in the UK, despite the differences between the two systems?
Just how much does not being fully metric cost the UK economy?
One of our regular readers, John Frewen-Lord, has compiled a quiz, or rather two quizzes, to illustrate the waste resulting from the UK’s measurement muddle. The editors of Metric Views are unsure why a penalty of £1 per second has been chosen when scoring the quizzes – this pay rate surely applies only to top bankers, Premier League footballers and workers changing traffic signs for the DfT. If readers are equally puzzled, John will no doubt explain. Anyway, pen, paper, calculator and timepiece at the ready please ….

Mesures usuelles. An anniversary remembered
The comment by Han Maenen on the previous article reminds us that this is the 200th anniversary of a decree which ended temporarily the use of the metric system for everyday purposes in France and elsewhere.

The generation gap
In his recent article “Why I …”, Ronnie Cohen looked at the present to explain why he believes the UK should complete the transition to metric units. However, some of those who commented on his article also looked back. In this article, I take another look into the past and then ask if the fading of such memories might prolong the measurement muddle.
Why I became involved with measurement matters
One of our readers has written to explain why he became interested in the campaign to complete Britain’s prolonged metric changeover.

Pound-inch units finally give way to metric in space
It looks as if astronauts, cosmonauts, or yuhangyuan as we will soon learn to call them, will before long have to cope with only one measurement system in space as the US winds down its programme and China takes its place.

Eurocodes for structural design, and that decimal marker
Britain is currently adopting European codes for structural design and allowing British Standard codes to lapse. This raises the issue of the preferred decimal marker – should imperial or continental practice be followed?

An ‘el’ of a standard
The powers that be of the metric system are wrestling with the problem of defining the kilogram independently of an actual physical object (i.e. the very slowly degrading cylinder of platinum-iridium alloy kept at Sèvres, near Paris, known as “the international prototype of the kilogram”). Meanwhile, they are neglecting a longstanding question that urgently cries out for a solution. [Article contributed by Martin Clutterbuck].
Snow calculations made simple, or not
One of our readers, John Frewen-Lord, has been housebound for four days by the recent heavy snow falls – about 60 cm deep in his area. This has prompted him to provide an illustration of the comparative simplicity of calculating snow loads in metric units.
