Metric. I was taught both too. But in my case we went metric for weights and measures and decimal for money.
Cruiser, I can only work out 1 Ton because I know it's 20 hundredweight and I know that a hundredweight is 112lb. Ask me what a ton is in lb and I'll pull out my phone and use the calculator. I do not have a numeric brain. Algebra, great, formulae? No issues, transposition of formulae? Absolutely. Basic numeracy? No chance that is what spreadsheets are for.... And, yes, I do know that you double each number and stick a zero on the end but I can't think of that when I see the question.
Just as I know a pint is 568ml and I can work it all out from there. When they taught me conversion at school they said 1" = 2.5cm. No it doesn't, it == 2.54. Which means a foot is 30.48cm and not 30 as they wanted me to believe. Also 1 gallon (imperial), = 4.54l. From there I work everything out, with the help of a phone with a calculator on it.
For those who like fractions, Pi is 3.14159 etc. But 22/7 is 3.142 which is close enough for most of us.
Anyway. Getting a long way from cancelling your direct debit.... But closer to why people can't see where their money is going once they moved to the much simpler Decimal money system and metric measurements. The brain ossifies when not used.
