  2. Fahrenheit - Wikipedia

    en.wikipedia.org/wiki/Fahrenheit

    c °C to f °F: f = c × 1.8 + 32; f °F to k K: k = ⁠ f + 459.67 / 1.8 ⁠ k K to f °F: f = k × 1.8 − 459.67; There is also an exact conversion between Celsius and Fahrenheit scales making use of the correspondence −40 °F ≘ −40 °C. Again, f is the numeric value in degrees Fahrenheit, and c the numeric value in degrees Celsius:

  3. Conversion of scales of temperature - Wikipedia

    en.wikipedia.org/wiki/Conversion_of_scales_of...

    * Normal human body temperature is 36.8 °C ±0.7 °C, or 98.2 °F ±1.3 °F. The commonly given value 98.6 °F is simply the exact conversion of the nineteenth-century German standard of 37 °C. Since it does not list an acceptable range, it could therefore be said to have excess (invalid) precision.

  4. Temperature - Wikipedia

    en.wikipedia.org/wiki/Temperature

    This definition served the following purposes: it fixed the magnitude of the kelvin as being precisely 1 part in 273.16 parts of the difference between absolute zero and the triple point of water; it established that one kelvin has precisely the same magnitude as one degree on the Celsius scale; and it established the difference between the ...

  5. Degree (temperature) - Wikipedia

    en.wikipedia.org/wiki/Degree_(temperature)

    Common scales of temperature measured in degrees: Celsius (°C) Fahrenheit (°F) Rankine (°R or °Ra), which uses the Fahrenheit scale, adjusted so that 0 degrees Rankine is equal to absolute zero. Unlike the degree Fahrenheit and degree Celsius, the kelvin is no longer referred to or written as a degree (but was before 1967 [1] [2] [3]). The ...

  6. Negative temperature - Wikipedia

    en.wikipedia.org/wiki/Negative_temperature

    The possibility of negative temperatures was first predicted by Lars Onsager in 1949. [4] Onsager was investigating 2D vortices confined within a finite area, and realized that since their positions are not independent degrees of freedom from their momenta, the resulting phase space must also be bounded by the finite area.

  7. Degree of frost - Wikipedia

    en.wikipedia.org/wiki/Degree_of_frost

    "Degree" in this case can refer to degree Celsius or degree Fahrenheit. When based on Celsius, 0 degrees of frost is the same as 0 °C, and any other value is simply the negative of the Celsius temperature. When based on Fahrenheit, 0 degrees of frost is equal to 32 °F. Conversion formulas: T [degrees of frost] = 32 °F − T [°F]

  8. 2 Degrees Will Change The World - The Huffington Post

    The green, orange and yellow lines indicate how surface temperatures will likely respond if leading carbon emitters begin to reduce reliance on fossil fuels. Without immediate curbs, temperatures are set to follow the red track, and increase between 3.2 and 5.4 degrees Celsius by 2100. The green line shows how we can minimize warming if ...

  9. Rømer scale - Wikipedia

    en.wikipedia.org/wiki/Rømer_scale

    [2]: 31 [4] At some point, the quarter degrees became whole degrees and Fahrenheit made other adjustments to Rømer's scale, modifying the freezing point from 7.5 degrees to 8, which, when multiplied by four, correlates to 32 degrees on Fahrenheit's scale [3]: 73 The 22.5 degree point would have become 90 degrees, however, Fahrenheit rounded ...
