Who under the age of 40 was taught the Imperial System? I've no idea how heavy an ounce is, how many feet to the liquid groat there are.
Can't wait 'til these Luddites die out and I can finally say my top speed is 7.5x10^6mm/hr. Now that's a number I can relate to.
When I went to school we were not taught the metric system but I know it so why don't you know the imperial system?
Do you drink beer? It's sold in pints and half pints - imperial
Do you look at road signs? They are in miles - imperial
Do you buy trousers? Waist sizes in inches - imperial
Do you buy shirts? Sizes in inches - imperial
Do you own a mountain bike? What are tyres and tubes measured in? Imperial.
Fuel consumption? Miles per gallon
Do you think that learning ends when you leave full time education? Can you do quick mental arithmetic with your built in calculator - also known as a brain?

When I see a road sign that says Toytown 18 I think "ah, Toytown is 18 miles away", not get out me calculator and go "hmm, Toytown is 28.9km away"!
What's the simplest way to roughly calculate how far Toytown is away? You can multiply by 1.6 but keep it easy and multiply by 1½. Half of 18 is 9 so 18+9 = 27kms and that's rough calculating! If you want to work it out another way 5 miles = 8 kms so round it up to 20 miles and there are for 5's in 20 so 4x8=32 so you know it is between 27 and 32 kms - call it 29½ and you are not far off - easy!
Other quick conversions:-
1 litre = 1¾pints - call it 2 pints!
1Kg = 2 lbs (pounds) or just a bit more than 2 lbs
1oz (ounce) = 30 gram(me)s
2½ cms = ! inch
So in school, I was taught Imperial, when I started nursing, we used the apothecaries' system, later in my training we changed to metric, I picked up metric on the way and also Thai traditional measurements.
All three of my daughters (all under 40) are conversant with Imperial & Metric and there is no reason why everyone shouldn't be!
