Some very nice information design going on in the top example from Ken Garland’s Portfolio.
When I was in grade school the U.S. was trying to convert to the metric system. Obviously, it didn’t quite work out as planned. We used to have metric study sessions for a few years when the conversion attempt was at it’s strongest, but it seemed to sort of lose steam by the time I got to middle school. It’s really a shame; inches suck, and so do quarts. The conversions and units never really make sense, they’re always these arbitrary ratios. Metric is so clean, you can deduce any conversion based solely on the latin prefix and you don’t have to factor in the length of some king’s foot when you’re trying to measure things. But I guess that all goes without saying. Everyone else also have way cooler plugs than us, but that’s a whole other post.
