  2. Conversion of scales of temperature - Wikipedia

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

    This is a collection of temperature conversion formulas and comparisons among eight different temperature scales, several of which have long been obsolete.. Temperatures on scales that either do not share a numeric zero or are nonlinearly related cannot correctly be mathematically equated (related using the symbol =), and thus temperatures on different scales are more correctly described as ...

  3. Fahrenheit - Wikipedia

    en.wikipedia.org/wiki/Fahrenheit

    A temperature interval of 1 °F was equal to an interval of 5 ⁄ 9 degrees Celsius. With the Fahrenheit and Celsius scales now both defined by the kelvin, this relationship was preserved, a temperature interval of 1 °F being equal to an interval of 5 ⁄ 9 K and of 5 ⁄ 9 °C. The Fahrenheit and Celsius scales intersect numerically at −40 ...

  6. 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]

    A few of inches of snow on top of a field can keep winter wheat’s crown (which is still underground this time of year to withstand the winter) at 28 degrees Fahrenheit (minus 2 Celsius) even if the air temperature is as low as minus 40 Fahrenheit (minus 40 Celsius), said Jochum Wiersma, an extension professor at the University of Minnesota.

  9. Scale of temperature - Wikipedia

    en.wikipedia.org/wiki/Scale_of_temperature

    The degree Celsius (°C) can refer to a specific temperature on the Celsius scale as well as a unit to indicate a temperature interval (a difference between two temperatures). From 1744 until 1954, 0 °C was defined as the freezing point of water and 100 °C was defined as the boiling point of water, both at a pressure of one standard atmosphere.
