Here's a tiny quote from a New York Times
article (about Britain and Ireland being able to keep using pints) that made my blood boil:
...the United States, one of three countries, including Liberia and Myanmar, that have not officially adopted the metric system.
What glorious company we keep these days. The metric system will never feel as comfortable and natural to us who grew up with inches and ounces, but there's no reason the next generation has to feel such awkwardness. Comfort with the metric system would be a great gift to pass on to our children. Given the crap we're handing off to them in other areas (climate change, national debt, etc.) it's the least we can do.
