Do scientists use farenheit? Genuine question
- muhbags 8y agoNever. It's either no units (theoretical physics), eV (particle physics) or Kelvin/Celsius for experimental physics.
- ravar 8y agoTechnically there is Rankine if you want to do thermo in imperial units.
- EForEndeavour 8y agoTechnically, Rankine and Fahrenheit are not imperial units.
- godelski 8y agoI've only known engineers to use Rankine and they hate it. I've never known a scientist to use it.

- grogenaut 8y agoWhen they look at a weather report in the US. Otherwise no.
- jcranmer 8y agoYou forgot about oven temperatures as well.
- grogenaut 8y agoTouche. My aussie friend who was a scientist said when he was in the us for about 15 years that he still used c for temp in lab but F for weather and it took him a while to realize that he had flipped and the 2 things had basically no relationship in his head.
- puranjay 8y agoIt took at least two burned dishes before I realized the recipes I was following called for Fahrenheit, not Celsius
- nsxwolf 8y agoBurned dishes or burned houses?
- selectodude 8y agoWhat kind of fusion reactor of an oven do you own that goes up to 425 degrees Celsius?
- Arbalest 8y agopyrolytic perhaps?
- ToFundorNot 8y agoSlight tangent, but Frank Stronach of Magna International, started his business smelting parts in their modified kitchen oven.
- sandworm101 8y agoSome. Not the physicists or astronomers, but some Americans who work with data from non-scientists regularly stay with the units in the data. Some engineers, those who are dealing with older equipment, stick with the units used when the equipment was built. US pilots and aerospace generally still talk in knots and feet of altitude.
- pc86 8y agoI fly a '76 Cherokee pretty regularly and its ASI is in both knots and miles per hour, with MPH actually being the more prevalent unit.
- jschwartzi 8y agoMountain climbers in the US typically also use feet for elevation. Compasses sold in the US also have different markings for measuring the Universal Transverse Mercator grid(1:24,000 and 1:50,000 in the US) and rulers(inches, feet). 1:24,000 is used on USGS 7.5-minute maps, and I believe 1:50,000 originates from an older map series, both of which have topographical lines marked in feet instead of meters. Altimeters sold in the US also customarily use feet although the digital ones can be switched to Meters.
- philwelch 8y agoKind of a tangent, but I still firmly believe that for Earth weather conditions, Fahrenheit is a more intuitive scale. 0 is a really, really, really cold day and 100 is a really, really, really hot day. 50 degrees is neither especially warm nor especially chilly, 70 degrees is warm, 30 degrees is chilly, 20 and below are truly cold, 80 and above are truly hot, and if you go into negative numbers or above 100 degrees than you're in the "extremes".
- bsaul 8y agoCold and warm are relative. 0 for freezing / snowing and 100 for boiling gives you a much more understandable range. Honestly, US metrics don’t make any kind of sense anymore...
- philwelch 8y agoExcept for weather, it’s never 100 C outside, or else we’d all die.
- TomMarius 8y agoYeah but it's still a very useful point where 100 should be, e.g. when you go to a sauna you know more precisely what to expect.
- thefringthing 8y agoWhile it's true that 100C doesn't have any weather meaning, 0F being "very cold" isn't particularly objective. I just looked it up, and apparently 0F is only about -18C. Whether -18C is "very, very cold" depends a lot on where you're from and what you're used to. I'm Canadian and I certainly wouldn't characterize -18C as "very, very cold". -30C maybe. 0C has a fairly objective interpretation in terms of weather: it's the point at which puddles start to freeze into ice slicks.
