> Zero being freezing is a critical number to know, because that's when you can get black ice (+/- wind-chill) and snow. For those of us who don't live somewhere that ever gets black ice, this is not a critical reason. Also, I suspect that wind-chill does not work how you think it works. > That said, all our appliances (oven, barbecue) use Fahrenheit and I have no idea what temperature to cook at in celcius. Spare a thought for those of us in enlightened civilisations that have to deal with myriad north-american based cookbooks ... but having said that, it'd take you a couple of weeks, with maybe a post-it note in the kitchen for the duration, to get the hang of the conversion rate.
