Welcome to our currency. (well the £/p one at least!) Yes the sizes are a bit odd - eg the 2p is huge while the 5p is tiny!
If you have any 2p's that are older than (guess) a few years then you'll hold coins that are worth more than their face value! This is due to the price of copper going up. A small 'interesting fact of the day' there. I also say they should dispense with 1p and 2p to hostile remarks from the other half. The problem is most things get priced up with .99 at the end. I always prefer checkouts that have a charity box nearby!

I wasn’t quite sure why they were needed, they made one too many to sort out. 1, 5, 10, 20 pence/cent, and 1 and 2 pound/euro, would have been fine for the coins. Also, the size increase wasn’t linear.

If I have a 50p coin I have half of £1 (£1 being 100 pence). I also have far too many 2p pieces. Fifty of them make up a pound (£1) Rather nicer is this £20 note. You can do the math(s) relating to all the other items above. If our currency was made up of just 1p pieces, £1 coins, £100 notes etc then you could just about start to apply metric principles to our currency and talk about decipounds, megapence, kilopounds etc. If I go to other countries I see similar attributes to their currency - although there is no currency which is stored in an office in Paris or whatever - although the dollar is the prototype of some currencies, you could say. Having said that, none of the other currencies have prefixes such as kilo, mega, etc either and none are based upon a scientific constant (in fact they change in value every minute of every day). Similarly I cannot divide or multiply my currency by another metric measure - although I suppose you could say that salary = X£/s "Decimal" is all that links our currency and metric measures. <Exit stage right> From: stevo.da...@btinternet.com To: usma@colostate.edu Subject: [USMA:47101] RE: Decimal currency & Metrication Date: Mon, 12 Apr 2010 14:36:47 +0100 Metric is base 10; decimal and decimal currency is base 10. Both divide up and down by units of 10: 5p - 50p - £5 5cm - 50cm - 500cm (or 5 metres). Both divide into decimal fractions of 10: £1.45 - £14.50 - £145 1.45cm - 14.5cm - 145cm (or 1 metre, 45cm) The only real difference is that you cannot divide decimal currency beyond the number 1. So, all in all, I would say decimal and metric are very similar indeed and work on the same principles. ----- Original Message ----- From: Stephen Humphreys To: U.S. Metric Association Sent: Friday, April 09, 2010 10:46 PM Subject: [USMA:47088] RE: Decimal currency & Metrication You could also say that 'base-10' is the only thing that links metric and decimal currency. On other levels there is very little commonality - For example - you can have a mixture of unit-types happening concurrently. In fact all countries are mixed unit (imp or USC and metric) - just to varying degrees, eg Germany has very little imperial - but still has it (BTU, inches) right up to the UK and then the US. In the latter two countries you can see a large mix of units operating concurrently. You cannot have a decimal currency and a non-decimal currency running concurrently. Maybe during a transition there are 'equivalences' but this simply makes non-dec currency equivalent to a a dec one. Some people say that money is a 'measure' of wealth. I think that's as far as the use of the word goes. Decimal and decimalization is a mathematical theory - ie 'decimal' is not a measurement. metric and metrication *is* a measurement topic. > Date: Fri, 9 Apr 2010 21:24:48 +0100 > From: tom.w...@tomwade.eu > Subject: [USMA:47087] Decimal currency & Metrication > To: usma@colostate.edu > > > > > I doubt it.
