I'm supposed to be working, and you, Mr Cameron, are forcing me to take time out. That is because you, Mr Cameron, are one prize, antiquated arse who came out the ark.
Last time I looked, you were (approximately) the same age as me. I started school in 1972 and I have never been taught imperial measurements. By the time I had had my kids I had just about sussed that it was some sort of mental system where you had 16 ounces in a pound, but only 14 pounds in a stone, so theoretically you can weigh something like 9st10lb15oz - FFS! As for inches and feet - there seems to be 12 of those in the other. What is wrong with a sensible system that simply counts to ten and one hundred? He cites the issue that kids have to calculate between the two systems... No, they don't, no one under 47 has learnt the old system so you know what - if on say medical forms you simply put a wee box saying Height: ---cm or Weight --kg, then no one would ever need to use a pound or foot again. It has not disappeared because you and your likes do everything you can to keep it in use. Scales actually all have a kg setting underneath, I set mine to it when I bought it in 1993 and haven't swapped it back since - simples! I refuse to calculate between the two. I know my kids' heights in centimetres and their weights in kilos but I haven't the slightest inkling what their imperial measurements are and no one else would either if scales no longer had a stones setting. It is time the old imperial system went the same way as the Empire itself. (It's dead, have you not noticed? Even half of Scotland wants out - that's the half that got beyond the BBC and the tabloids!)
Or better still, maybe when we finally get our independence, we can keep the pound and England could re-introduce the old, non-decimal money we used when I was a small child. Then, everyone would be happy.
