Facts and Curiosities

The Kelvin scale was proposed in 1848 by Lord Kelvin, who wrote an article on the need for a scale where the "infinite cold" (known as absolute zero) was the zero point of the scale. This point was set to -273.15°C. With this, the Kelvin temperature scale became the only one where there were no negative values. Unlike the Celsius and Fahrenheit scale, the temperatures described in Kelvin are not accompanied by the word "degrees". Therefore, one should not say 250 degrees Kelvin, but one should mention only 250 Kelvin or 250 K.


The Fahrenheit scale is a thermodynamic temperature scale, where the freezing point of water is 32°F and the boiling point is 212°F. This puts the water boiling and freezing points separated by exactly 180 degrees. This temperature scale was proposed by Gabriel Daniel Fahrenheit in 1724. To reach these values, he placed a thermometer inside a mixture of water and other chemical components. In the position marked by the level of the mercury inside the thermometer, Fahrenheit marked the zero point, then used the same thermometer to measure the temperature of the human body and thus marked the 100 point. Finally, he divided the space between zero and hundred in 100 equal parts. The Fahrenheit scale was born.
