A recent comment on UKMA’s Facebook page has prompted Metric Views to look into NASA’s latest mission to Mars. This is reported to have landed at 06:32 BST on Monday 6 August.
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.

In this article, I take another look into the past and then ask if the fading of such memories might prolong the measurement muddle.
One of our readers has written to explain why he became interested in the campaign to complete Britain’s prolonged metric changeover.
