Tyre pressure measurement

Maybe things would be better if we re-calibrated the inch every time we had a new Monarch, as it was originally the length of the King's thumb. Have you seen Charlie's hands?

As for fuel consumption - I find that litres/100km is so much more sensible than miles/gallon.

I don't really.

Always known that more miles/gallon is better so it is counter-intuitive to me to talk about litres/100km or kWh/mile where less is better.

That's because they are inverse things- litres/100km is consumption, miles per gallon is economy (1/consumption).

Economy is what we understand, so we ought to use miles per litre,or even miles per 10 litres might work.

My car does about 8 miles per litre, so I walk or cycle if I can!

In the aviation world, fuel is loaded in litres (or US Gallons) but converted to kilograms depending on the SG (specific gravity) on the day. Temperature is in Celsius or Fahrenheit, aircraft speed in knots (nautical miles per hour), wind speed in knots (or meters per second in some countries), height/altitude in feet or meters depending on country, altimeter settings in hectopascals in much of the world, inches of mercury in the USA and mm of mercury in some other countries. Climb and descent rates in feet per minute. Visibility in meters (feet and miles in USA).

Easy to get confused as the Gimli Glider pilots found.

I got a notification that a "fred" had posted in this thread, but the post no longer exists. I wonder what nonsense was being spouted?

And to circle back to (part of) the original question ... tyre pressures should be as per the tyre manufacturer recommendations, not necessarily what's printed in a handbook or on a wheel arch.  

LOL...."nonsense"... provided....🤣🤣

So you're admitting it was you who spouted nonsense in the EV thread then deleted your post? (I didn't identify anyone specifically).
