Apologies I was perhaps too much tongue in cheek, there was no offence meant. On the other hand, you too are arguing against points I haven't made. I'm not saying the imperial system is bad on it's own. I have no opinion on this. Anyone who is used to it will find it intuitive. However, saying that it's somehow objectively more geared for humans is also incorrect, because as I wrote it is exactly as convenient to use for people used to metric as metric is for people used to imperial. > the turning point between very warm and hot is literally built into the system at 100F. If you think 30C is hot, you’ve clearly not spent much time here in the summer... and it doesn’t feel really cold until you’re down around 0F anyway Again, this is subjective. 30C is hot for many people in the Nordics, and business as usual for someone in the tropics. The same will apply whether we use the imperial system or not. But I personally have no intuition how 0F or 100F feels like. It's all subjective (how it feels like). I was merely arguing that trying to lean on subjective/intuitive feel for the units to make a general case of them being useful for daily life is still just subjective. Imperial is intuitive for people who are used to it and highly unintuitive for anyone who isn't. Conversely, metric is intuitive for people who are used to it - even for daily life and imperial is not.
