All I know is I've dropped a few "stones" during this summer! Probably enough to make a boulder.
I fully comprehend the metric system and the Celsius scale but I still prefer the British Imperial system of weights and measures and I hope we never change.
I like my miles and inches and it will never sound right having a speed limit of 90 kilometers per hour or a snowstorm with 40 centimeters of snow. Likewise, I like my Fahrenheit. You do get a more accurate sense of how warm or cold it is with Fahrenheit simply because the scale is larger.
As for stones, well the British can keep their stones.
Personally, I don't think it matters which system a nation uses as long as they stick to one thing or the other. At the end of the day, temperature is always going to be some lines on a thermometer with corresponding numbers. To get more accurate on the Celsius scale you need to get into decimals where as with the F scale you needn't right away.
While, I personally prefer working with metric numbers for weight and length because it's just easier and simpler I grew up with the US system and will always think of some things in those terms (height of a person for example). By easier to work with, I mean- if you want to figure out how many inches are in 768 miles, you're going to have to break out a pencil and paper and do some multiplying. If you want to know how many meters or centimeters are in 768 kilometers you just have to add some zeros correspondingly (768,000 and 76,800,000 respectively are the solutions). Same with weight. This is why we use the "metric" system with US Dollars.
Anyway, what a nation really doesn't want to do is get into a system where they are using odds and ends from two systems which is exactly what the Brits do. They use miles for long distances but metric for short ones. So something might be 3 miles down the road but your ceiling is 2.4 meters high. They use pints (20 ounces) in the pub but liters in the petrol station. They use stone (which breaks down into lbs and ounces) for personal weight but kilos for damn near everything else. And of course, they use Centigrade for temperature. It's really weird. I wish they'd go to one or the other and stop using both.
but I still prefer the British Imperial system of weights and measures and I hope we never change.
(as pointed out earlier, even the US doesn't use total British measure- a US gallon is smaller than a British one)
