A better use of multiples?

To ease the transition to metric measures, straight substitution of units is often used – kg for pounds, metres for yards, km for miles and so on. Ronnie Cohen argues that, as a result, we fail to take advantage of metric’s superiority in dealing with a range of numbers, including the very large (and small).

The UK Department for Transport (DfT) now puts forward cost as the principal reason for the failure to convert road traffic signs to metric.

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?

Goodbye Imperial. Hello British weights and measures

We, the public, are encouraged by some politicians, by the DfT and by elements of the media to pick and mix our measurement units – to use both imperial and metric. So why has imperial as a system fallen from favour among those resisting change, and been replaced by a hybrid?

Speed, momentum and resistance

Which is preferable: a swift metric transition or a leisurely one? UKMA would have preferred the former. Successive UK governments have opted for the latter, believing that it carries less risk to their popularity. Ronnie Cohen assesses progress.
