#OTD 56 years ago, 👨🚀 man first landed on the Moon 🌑
MYTH: NASA didn't use the #metric system to go to the Moon
FACT: The Lunar Module’s onboard Apollo Guidance Computer used SI units during the computer-controlled phases of the craft’s descent to the Moon

Fun fact: Before Europe went metric in the 1870s, Norwegian, Swedish, Amsterdamse, Preussian, Bavarian, Saxon, Württemberg, Viennese and imperial feet and inches were all different.

Road designers and contractors use metric. The distance marker posts at the side of motorways are at 100m intervals, which aid contractors when installing roadworks signs. It doesn't make much sense to still be using yards on the signs themselves.

The roadworks signs say yards, but the actual distances are in metres.

I work with these type of measurements in my work but not in Imperial, no one on the planet, except the US, use Imperial in the design & construction industry. We use it then the press realase convert it back to Imperial. Pathetic really seeing the UK are a metric country officially. 🙄

I am in my 50s and was never taught the imperial system at school. Why on earth is the transition to metric taking so long. It's got to be holding the country back.

If we had just actually properly kept on with the original plan of going fully metric (like the rest of the British Commonwealth did), we wouldn’t even have this crazy problem… @ukma.org.uk

This can still happen though, as the pressure for England to reduce urban speed limits is not going away.
#Metric speed limits also have the added benefit that they provide highway authorities with a greater range of available speed limits to choose from.

Yes, we realise that Wales could not switch to km/h independently from the rest of the UK.
But, with some forward thinking in Westminster, the safety benefits of reducing urban speed limits could have provided the excuse needed for the Government to change all UK speed limits to metric.

The cost can be reduced if the speed limit reduction takes place at the same time as a switch to metric speed limits.
“30” signs could be retained, but perhaps with the addition of a temporary “km/h” plate.
Metric also provides a more flexible range of speed limits.

Opportunity missed to save £ millions on new speed limit signs in Wales
An opportunity to save millions of pounds on new speed limit signs in Wales has been missed by the failure to synchronise the lowering of the default speed limit on roads in built-up areas in Wales…
