I also found that W6 country doesn’t know meter or kilometer unit.
Yes, just like articles in QST, all measurements in inches etc. It’s quite entertaining using metric measurements when in the USA and seeing the baffled look on faces. The use of imperial measurements is probably more of a problem for mainland Europeans than UK hams as we are used to using both systems in parallel. In the UK the majority of measurements are now metric with the engineering industry having gone metric a long time ago. But I can still go into a shop and ask for 1/2 pound of cheese and I’ll be served somewhere around 200-220 grammes.
Petrol has been sold in litres for I think about 10 years yet 30 years of driving experience means I calculate fuel economy to miles per gallon as road distances are still measured in miles. With miles per gallon, bigger is better but the favoured metric measurement of l/100km means smaller is better which feels wrong.
Walking is a strange mixture for me, UK maps are metric so I know how far a km is to walk and how long it will take me. I know how much effort is needed to climb 100m. But I think of the distance to drive to a hill in miles. Express walking distances in miles and heights in feet and I have to work back to metric units. So for some measurements I’m converting metric to imperial and for others imperial to metric. It still confusing when looking at UK maps over 35 years old which are not metric.
You could say we should just use metric measurements and the response is we do most of the time. Where most UK people get annoyed is being forced to change because some political dogma insists on it. It’s not a problem for us to run both systems. Most Europeans can speak English as well as people in the UK whereas most British people have almost no ability to speak other languages. So we stick to using archaic measurements and using confusing speech dialects to maintain our (misplaced) feeling of superiority over other countries
