As I progress on my journey, I speak with a number of British people. Most of these people are younger than me; some by only a year, but some a good 5-6 years.
They don't understand weights in metric. They can't comprehend what it means when someone says, 'I'm 80kg', but when the same person converts to imperial – 12st 7lb – suddenly it makes sense to them.
I went to school between the years of 1984 and 1996 (yes, just the twelve). I wasn't once taught stone, lbs, oz. I grew up knowing that 'person weight' is for some reason measured in stones, but that, I believe, is due to the generation we were reporting to knowing imperial more than anything. Now, everything to me is metric; it's a chore to convert to old-school.
But why does the current generation of people in their 20s and 30s continue to use imperial? It makes no sense.
This is of course only directed to people in the UK. For some unknown reason, the US is stuck in imperial (or statute) hell for the foreseeable. Then again, they picked Bush for president, so I don't think that's surprising.
So, I plead with you: act your age, move with the times, embrace the metric, it makes things easier overall.
