Here's my impression of those temperatures:
0F - Have seen this once or twice abroad and was too wowed by the novelty to feel any discomfort from the cold, though it was clear and calm and I was wearing virtually every piece of clothing I had. Some frost-prone places in the UK got this before Christmas, but the law of averages says they won't again for many years to come.
10F - Would be the record low for London in the era of reliable recordings, but I have experienced this a few times up north. Generally isn't that bad, because to get it you need clear, calm skies and snow cover and you'd be bundled up because when we get this sort of thing the weather would be the main topic of conversation. Riding a bike in it stings you regardless of how low the winds are.
20F - for the average place in the UK this will be close to the lowest temperature of the winter, so clear, calm conditions. I've seen this abroad though in overcast, windy conditions and was very unpleasant.
30F - if we get this during the day and it's sunny it feels invigorating, if it's overcast and windy then bleak as hell. The average place in Britain gets this as their coldest daytime high of the year, and I'd wear a hat, coat and gloves.
40F - Typical boring winter temperature. Would just wear a coat.
50F - on a sunny, calm day in February/March it feels very pleasant (i.e. today) and I'd have no problem going out in a T-shirt. I've seen a July high in the low-50s up north and it felt miserable.
60F - to get this in April would be pleasant because it would be sunny, to get it in July unpleasant because it would be wet/windy.
70F - typical summer day for most of England, though to get this up north feels better because it would generally be sunny, whereas to get this as a daytime high in July in London would need showery, overcast conditions for much of the day. Older people start to use the Fahrenheit scale to emphasise how warm it is.
80F - Ideal weather if you don't have to work in it or do anything that energetic. In my experience comes with mostly sunny skies, with a thunderstorm at the end of it. Is normally the hottest day of the year in the north, a standard midsummer warm spell in the south.
90F - Generally the hottest day of the year in the south, hottest day every 15-20 years up north. Too hot to go about everyday life really, as few places here have air-conditioning. The London Underground becomes a sauna (it's bad enough when it's 70/80 outside), and the weather will be the main topic of conversation. Mornings/evenings are beautiful, though nights will be hard to sleep. Crime rates often go up in prolonged heatwaves.
100F - people used to say it was impossible here but has happened on one day in the UK, in and around the London area. I wasn't here to see it, but some road/rail surfaces melted, power cables sagged, and somebody I know from Uganda said it was the hottest he'd ever experienced because of our higher humidity. Something best left to the climates used to it IMO.
