Fahrenheit vs. Celsius

You have to admit, it's got a point!


  1. The Fahrenheit scale is a better tool for conveying the human experience of temperature, the other two, not so much, but their strength is in scientific conveyance.

  2. Well, it looks like I want the temperature to be Celsius in winter and Fahrenheit in summer. I think I'll write my Congressman suggesting it.

  3. Fahrenheit scale for journalists*

    just weather.................................climate change

    *IPCC approved

  4. You forgot the Rankine scale, which is the US equivalent of the Kelvin scale.

  5. Nicely illustrates why I find Metric to be superior in virtually all circumstances except every day temperature. Being able to tell how the weather feels without getting into decimals is pretty nice!

  6. You can do weather temps in Celsius without decimals; it just takes a little familiarity to learn the conversions.

    40 C (104 F): freakin' hot
    30 C (86 F) : hot
    20 C (68 F) : warm
    10 C (50 F) : cool
    0 C (32 F) : freezing
    −10 C (14 F) : cold
    −20 C (−4 F) : freaking' cold

  7. I prefer the LC scale.

    LC = 4 - C/10

    C = degrees Celsius

    LC = number of Layers of Clothing optimal for comfort

  8. LC = number of Layers of Clothing optimal for comfort

    I've found that the shirt fabric makes a huge difference for whether a shirt is uncomfortable in high heat. For example, the wicking fabric in the Walls shirts sold at Walmart are much more comfortable in high heat:


  9. I find I use Centigrade for some science things, Fahrenheit for others and daily stuff, the sporadic Rankine and Kelvin for chemistry problems ( I learned chemistry in Rankine... long ago...) But have developed a recent fondness for the Newton Scale..

    Then there is the old Russian Delisle scale that runs backwards (as did the original Celsius scale)


    nice comparative chart here:


    indcluding the similar sounding but different
    Rømer and Réaumur scales.

    Go back into the old "raw" data and you will find these and perhaps even a few more...

    The Delisle is interesting as it was created by a Frenchman, but used in Russia for 100 years or so. Water boils at 0, it is a hot day at 100 (about as hot as you will get in Russia) and it is open ended to the downside with ever larger numbers for the ever greater cold in Siberia... "fit for purpose" as it were ;-)

    It is the notion that the only way to measure things is from a European Committee that is broken... As long as you have the conversion tables, any system is fine.

  10. n-g;
    Your LC scale says naked at 40°C, -1 layers at 50°C. Sounds painful!

  11. Sorry, just a matter of education and habit. Living in a "Celsius" world, as I live, means that you go from 0 - 40. It's compact. Less is more... :-)
