A total of 8 temperature scales have been added here, that is conjugated by the equations:
$$\frac{C}{5}=\frac{F-32}{9}=\frac{K-273.15}{5}=\frac{R-491.67}{180}=\frac{150-D}{150}=\frac{N}{33}=\frac{Re}{80}=\frac{R\phi-7.5}{52.5}$$
where, the scales, as systematically arranged are:
Celsius [\(C\)]: The Celsius scale, (or centigrade scale), is a temperature scale based on \(0^o\) for the freezing point of water and \(100^o\) for the boiling point of water. This scale was first introduced by (and is named after) the Swedish physicist, astronomer, and engineer
Anders Celsius.
Farenheit [\(F\)]: The Fahrenheit scale is a temperature scale based on one proposed in 1724 by the physicist
Daniel Gabriel Fahrenheit. It uses the degree Fahrenheit as the unit.
Kelvin [\(K\)]:The Kelvin temperature scale is an absolute temperature scale [with no negative values] with zero at absolute zero. Because it is an absolute scale, measurements made using the Kelvin scale do not have degrees. The kelvin (note the lowercase letter) is the base unit of temperature in the International System of Units (SI).It is named after physicist
Lord Kelvin.
Rankine [\(R\)]:The Rankine scale is an absolute scale of thermodynamic temperature named after the University of Glasgow engineer and physicist
Macquorn Rankine, who proposed it in 1859.
Delisle [\(D\)]:A temperature scale that sets a fixed zero point equal to the temperature of boiling water. The Delisle scale is uses incrementing degrees as the temperature decreases. It runs from 0 degrees at the boiling point of water to 150 degrees at the the freezing point. [Inverse relationship with almost every temperature scales]. First discovered by physicist
Joseph Nicholas Delisle.
Newton [\(N\)]: A deprecated scale developed by
Sir Isaac Newton in 1701. The relationship between this scale and the others is pretty much erroneous.
Reaumur [\(Re\)]:The Reaumur scale is a temperature scale in which the freezing and boiling points of water are defined as 0 and 80 degrees respectively. The scale is named after the physicist
Rene Reaumur who proposed it in 1731. The unit associated with the scale is called Reaumur, usually abbreviated "Re".
Rømer [\(Rø\)]: A different scale from that of Reamur, it is a temperature scale named after the Danish astronomer
Ole Christensen Rømer, who proposed it in 1701. It is based on the freezing point of pure water being 7.5 degrees and the boiling point of water as 60 degrees.
A more sophisticated equation can be added to here: $$313.5 K = 40^o C = 104^o F = 563.67^o Ra = 28.5^o R\phi = 13.2 ^o N = 90 ^o D = 32 ^o Re $$ Source: Wikipedia
