You buy fuel priced in Litres but if you fly a US manufactured aircraft (e.g. Piper) the fuel/consumption figures are in US Gallons (not the same as UK Gallons). However before you can fly you need to know the weight of the total fuel (and all people & baggage) in pounds. To get the weight in lbs you need to convert the total fuel volume back into L because the specific gravity of the fuel is in Kg/L which gives the weight in Kg which you then need to convert to lbs to ensure both the weight and the centre of gravity is within limits as specified by the US manufacturer.

Thanks for that. I think.

A brief toe dipping into the sea of UK General Aviation for pilots of single engine piston aircraft:

Vertical measurements – Altitude, height above ground, cloud base, clearances etc are all in feet, however horizontal measurements are not – Visibility is in metres and distance between two points is in nautical miles. A nm is one minute (1/60 of a degree) of latitude however this changes and so it’s 1852 metres which is 1.151 ordinary/statute miles.

Pressure is in hectopascals where 1hPa is exactly equal to 1 millibar.

After this the actual volume is replaced in your head by endurance anyway – full tanks will last a known number of hours.

Oil is measured in Quarts but I have no idea how much that is – It’s just notches on a dipstick.

And a Radar mile is 12.35 µs (cos it measures there and back).

I wonder what would happen and who would pay for changing all the road junctions, markings and signs Sweden at the time didn't have much of a road network and there was mayhem. For us the mayhem would be in another league never mind the costs. Anyway a lot of the world drives the correct side of the road such as Japan, Australia, New Zealand, South Africa and various other Countries. Are Japanese cars more expensive in the US and EU because they drive on the wrong side of the road?

I think this is one of those things that if you just commit to it, isn't such a big deal as it might seem - there can be workarounds and so on.
But why bother. In a short time it'll all be driverless.

In contrast with an unelected Queen and unelected House of Lords?

And the elected house trumps all.

If we were to go fully logical then we would ... use right hand drive vehicles. Sweden did it with minimal fuss and benefited for years after from cheaper import car prices.

If someone came to England and was learning English and mathematics, it would be very easy to explain the metric system. Even if you they haven't used the concept of kilo/centri/milli in English or maths before it is self explanatory and easily understandable.

The issue with imperial measurements is that they require people to remember specific numerical values for multiplication and division between the other measurements. There are no simple prefixes. Worse still was that the measurement per unit differed between countries. This worked well enough when the population mainly stayed in England and international travel was a rarity, but in a modern world imperial is a very silly system of measurement.

If we were to go fully logical then we would switch to kilometres and use right hand drive vehicles. Sweden did it with minimal fuss and benefited for years after from cheaper import car prices.

The US don't use stones and some of their other imperial measurements are completely different weights/measures to UK ones e.g a ton.

That's ok, most small retailers in the UK didn't typically sell in stones/tons anyway, only pounds and ounces. You might have bought cooking products by hundredweight I suppose.

There's a handy table here to explain the difference. https://en.wikipedia.org/wiki/Compar...rement_systems

Neither of which have the authority to overturn Parliament...

And neither do the EU presidents have the authority to overturn the EU parliament, so that's alright then. Can we go back on topic now? Or must I attempt to move your posts and have them lost because the links break?

Neither of which have the authority to overturn Parliament, or we'd still be preparing for life in a federal European state.

I think you just press a button dear. Most electric scales still seem to support imperial, presumably due to the US.

We haven't left Europe, we've left the yet to be officially declared state of Europe, with it's unelected Presidents (and I've yet to hear a rational reason why it needs 2 Presidents, presumably one the French agree with, and one for the Germans).

I seriously doubt that small retailers are going to invest in imperial scales as it has taken them until Covid to get card readers..
