| Venus is room temperature with low radiation, if you dig in. Living on Venus was floating around as an easier alternative to living on the Mars surface. Room temperature is 21°C, I have no idea how many freedom fries units that is. |

| A shockingly useful "quick and dirty" estimate for C to F for temps humans are likely to encounter is 2x + 30. It's not precise at all, but for purposes of "what does that feel like outside" or "should I bring a sweater" it works pretty well. 21C would, by this estimate, be 72F. The true conversion is just shy of 70F, so, again, it's not correct but it's close enough for this kind of conversation. |

You get: -40F=-40C -22F=-30C -4F =-20C 14F =-10C 32F = 0C 50F = 10C 68F = 20C 86F = 30C 104F= 40C and then approximate in between from there. It's quick enough for me now that I skip the 2x+30. | | |
| ▲ | abduhl 3 days ago | parent | next [-] | | In this HN subthread: users slowly converge on the conversion formula for Celsius to Fahrenheit (32+9C/5) in greater and greater precision while calling it an “approximation.” | |
| ▲ | freedomben 2 days ago | parent | prev | next [-] | | Always interesting what's easier for some people. Personally 9/5x + 32 is much easier for me to remember and calculate | |
| ▲ | noslenwerdna 2 days ago | parent | prev | next [-] | | These points make it easy to remember for me, adding ~5C for 10 F. 40 F = 4 C (forty is four) 50 F = 10 C 60 F = 16 C (sixty is sixteen) | |

27c is 81f (it's all threes!) |

0 = freezing
10 = chilly
20 = comfy
30 = warm
40 = scorching. | | |

| The Fahrenheit scale is European, not American. It was created in Poland well before the United States broke off from Great Britain. We're just slow to change. |

| ▲ | vjvjvjvjghv 2 days ago | parent [-] | | Maybe there is a reverse psychological angle to make the current US administration go metric. Fahrenheit->Polish->European->Communist/Woke. Can't have that! | | |
| ▲ | palmotea 2 days ago | parent [-] | | > Maybe there is a reverse psychological angle to make the current US administration go metric. Fahrenheit->Polish->European->Communist/Woke. Can't have that! 1. That nonsensical, because the same logic would apply to Celsius temperatures. 2. Americans don't keep using Fahrenheit because of some aversion to Europe. Though I do have some fondness for it as resistance to the machine-people who are always going on about efficiency and trying to hurry everyone up. |

| The irony is that (at least I'm pretty sure) the concept of "room temperature" was originally pinned to 70° Freedom Degrees. Your 21°C reference unit is probably a rounded conversion, which explains the sibling comment arguing 23°-25°C as potentially inferior alternatives. An accurate conversion would be 21.1̅°C. |

| ▲ | bryant 3 days ago | parent | next [-] | | Imperialist here. Freedom fries was funny. | | |
| ▲ | yndoendo 3 days ago | parent [-] | | Had to add metric to an imperial unit application since it is to be sold internationally. I live in a Fahrenheit country so I set my phone, computer, and car to Celsius to learn how the the temperatures readings feel. I 100% agree, "Freedom Fries Units" is quite fitting. Turns out I prefer Celsius over Fahrenheit in day to day usage. |

| ▲ | antonvs 2 days ago | parent | prev [-] | | The US doesn't use Imperial units. It uses US customary units, which are different from Imperial in several significant ways, because the Imperial system evolved after the US split from the British Empire. Also interestingly, US customary units are defined in terms of metric. So in a sense, the US does use the metric system. https://en.wikipedia.org/wiki/United_States_customary_units | | |
