Our awkward, dual measuring instruments

As a consequence of the “very British mess” with measurement policy, the public has to put up with awkward, cluttered, hard-to-read dual measuring instruments. Various types are used every day. In this article, Ronnie Cohen describes several examples and comments on their impact on our daily lives.

The flip side of SI

Charlie P, a regular if occasionally critical contributor to MV, promised he would on his return from holiday give his thoughts on “the flip side of the SI as far as the average man in the street is concerned”. These now appear below. They are of course not endorsed by the Editors of MV, but may provide food for thought.

New breakthrough for the kilogram

In this article about new scientific developments to redefine the kilogram and remove its link to a physical object, Ronnie Cohen writes about recent reports about a new scientific breakthrough in getting the most accurate estimate of Avogadro’s constant to date, which can help to redefine the kilogram. These reports have been published in the last few weeks and you can find a list of sources at the bottom of this article.

Whitworth’s forgotten legacy

Whitworth is famous for the eponymous screw thread, and for his promotion of standard measures and interchangeability that brought about an engineering revolution. Less well known are his enthusiasm for decimal measurement and his opposition to the introduction of the metric system in Britain.

A Biblical specification and a problem solved (almost)

We are justifiably proud in England of the legal principles laid down in Magna Carta in 1215, but less supportive of its command, “Let there be one measure …”. However, weights and measures laws are as old as civilisation. In this article, Ronnie Cohen looks at a unit of length from 3000 years ago, and makes a comparison with today.

Has SI delivered?

The fuss about measurement units at the start of this century has overshadowed progress thirty years earlier in education, science and engineering. We look at the benefits that were predicted at the start of the transition to SI and ask if they have been delivered.
