Are you saying those of us within reach of a century should not be a member of this forum?

Absolutely, and when it comes to long distances it is miles for me. The same applies to speed and distance signs. I think they will probably be the last to go metric, if ever.

Weight? Well, when you buy most products they seem to come in g and kg but fortunately I don't buy a great deal by weight. Marge's compost, for example, is really more to do with the apparent size of the bag and when I have bought a bag of sweets I have asked for a 'quarter' (of a pound) and the shopkeepers seem to understand.

Capacity? I still ask for a pint and I have yet to see any pub which sells beer in litres. On the other hand, a bottle of beer is often 330ml and, I assume, looks like a little more than a half-pint. I suppose it is all about what you're used to.

Strangely, when it comes to length measurement, I always think of feet and yards when it is something around room size or more, including road distances as above.
However, when I want an accurate measurement of smaller lengths, I find cm and mm much easier. Eighths, tenths and sixteenths of an inch become far too confusing!

My speedo doesn't have irrelevant nonsense on it just Kph - makes it far less cluttered and easier to read. Why on earth you have both is beyond me.

What's a Pooka?

Is is worse than a Leprechaun?
