Newton scale

The Newton scale is a temperature scale that was proposed in 1700 by Isaac Newton. When Newton dealt with the problem area of the heat, he developed a first qualitative temperature scale, to " glowing coals in the kitchen fire " about 20 scale points possessed by "cold air in the winter ." This approach was crude and inaccurate, so that Newton quite quickly became dissatisfied with her. Since he knew the concept of thermal expansion, he used a container with linseed oil and measured the volume change with respect to the previous scale points. He put between the temperature of melting snow and boiling water down a volume increase of 7.25%.

After a while, he defined the zero point of his scale in melting snow (melting point, 0 ° C) and the 33rd degree than boiling water ( boiling point 100 ° C), so used the same fixed points as the Celsius scale, only with different degree intervals. A difference of one degree Newton ( 1 ° N ) therefore corresponds roughly to the three degrees Celsius.
