Guess the UK was a kind of half way house when it came to adopting metric measurements so that we still use old imperial measurements for some things (road signs give distances in miles and speed restrictions in mph, we more frequently use mpg, beer and milk is still sold in pints), others are in pure metric (Tetra pack drinks are sold in litres and sugar like many commodities is now sold in kg or gramms) but many are the nearest kind of rounded up/down metric equivalent (a lb jar of Jam is 454g, a gallon of paint is 5lt and timber lengths are 1.2/1.8/2.4m instead of 4/6/8 foot). Like Soulman, I still tend to use feet and inches when measuring for most things just as the better half still thinks in pounds/ounces in cooking. Weird when you think about it but I like the old imperial system as it's part of our heritage. I don't miss calculations in lsd but I do miss the old coinage I grew up with too.
