Apologies for the horrifically poor font kerning and hinting in those charts. I love LibreOffice for many things, but its inability to do font aliasing on charts is downright shameful.

As you can see, the curves all fit reasonably well, with R-square values above. I could have spent more time really tweaking the curves, but for purposes of photo manipulation these are plenty close enough. In the pseudocode above, note that Ln means natural logarithm. This function was used to generate the sample output near the start of this article, so I can guarantee that it works.

The image below — a promotional poster for the HBO series True Blood — nicely demonstrates the potential of color temperature adjustments. On the left is the original shot; on the right, a color temperature adjustment using the code above.

First, Neil B has helpfully provided a better version of the original curve-fitting functions, which results in slightly modified temperature coefficients.
His excellent article describes the changes in detail. Fahrenheit proposed his temperature scale inbasing it on two reference points of temperature.
In his initial scale which is not the final Fahrenheit scalethe zero point was determined by placing the thermometer in a mixture of icewater, and ammonium chloride salis Armoniaci.5. Celsius, Fahrenheit and Kelvin Scales (Hindi)
In any case, the definition of the Fahrenheit scale has changed since. Fahrenheit multiplied each value by four in order to eliminate fractions and increase the granularity of the scale.

He then re-calibrated his scale using the melting point of ice and normal human body temperature which were at 30 and 90 degrees ; he adjusted the scale so that the melting point of ice would be 32 degrees and body temperature 96 degrees, so that 64 intervals would separate the two, allowing him to mark degree lines on his instruments by simply bisecting the interval six times since 64 is 2 to the sixth power.
The use of the freezing and boiling points of water as thermometer fixed reference points became popular following the work of Anders Celsius and these fixed points were adopted by a committee of the Royal Society led by Henry Cavendish in Countries that use Fahrenheit.
Countries that use Celsius. The Fahrenheit scale was the primary temperature standard for climatic, industrial and medical purposes in English-speaking countries until the s. In the late s and s, the Celsius scale replaced Fahrenheit in almost all of those countries—with the notable exception of the United States—typically during their metrication process.
Fahrenheit is used in the United States, its territories and associated states all served by the U.
