Weights and Measures Act 1985 (Definitions of “Metre” and “Kilogram”) (Amendment) Order 2020

Lord Wei Excerpts

Wednesday 20th May 2020 Lords Chamber

[Lord Wei (Con)]

My Lords, I also thank the Minister for the clarity of his opening remarks. I welcome this change. I am going to disagree with the previous speaker and some of the others, because I believe that there is an interesting nuance to this measure and its context that goes way beyond the debate around the metric system versus imperial.

In fact, it is true to say that Britain and British scientists and thinkers have played a key role in developing the metric system, with the likes of Kelvin and, more recently, Kibble, who developed some of the techniques that have led to the current definitions that we are discussing today. Undoubtedly, in future the accuracy that this change will bring will be of great benefit in many fields: astronomy, quantum physics, computing and telecommunications, as well as more generally in business.

To me, this measure starts to potentially exemplify a positive trend towards decentralising control. No longer will we need to reference a lump of metal in Paris; we can actually develop our own understanding of these measures in laboratories in Britain. I am therefore saddened that the Explanatory Note says that we have to align with Europe in order to develop these standards. We were part of developing this system, so I do not think we necessarily need to reference any other country. In my view, we need to be able to make our own decisions, especially with Brexit, sovereignly about what measures we want to move forwards, and if our choice is to align with international standards then that should be our choice.

I have a question for the Minister: until recently there were apparently only two laboratories in this country that had the instruments to do these measurements. I would be keen to know whether there are more labs that have been equipped, resourced and encouraged to make these measurements on a regular basis around the country, so that we can decentralise even away from London or wherever we take our national standard from, and local communities, local scientists and manufacturers of weight and measurement instruments can actually develop these standards in accordance with the natural norms of the Planck measurement and so on.

I welcome this move and, while I would not say that it is necessarily about internationalism, although it is good to have common standards for trade, I would encourage the Government to give us clarity in the coming months and years on how we will develop our own sovereign decision-making on this. For example, will future decisions on changes are made to this system and others fall under the purview of chief scientists?
