While Fahrenheit is a widely used temperature scale in the US, most other countries have already switched from Fahrenheit to Celsius or have always used Celsius. In scientific circles, even in the US, only Celsius (and Kelvin) are used. |

− | [[Randall]] | + | [[Randall]] choose to name his new unit of temperature Felsius (a {{w|portmanteau}} of Fahrenheit and Celsius). Comically enough, this fictitious Felsius system of measurement discards all of the advantages of either system of measurement - the Celsius scale is based around 0 °C as the melting point of water and 100 °C as the boiling point, which Felsius does not preserve. Fahrenheit is often argued to be a convenient temperature measure for human comfort, as 0 °F is very cold and 100 °F is very hot. Many places on earth which humans inhabit fall well within these extremes the majority of the time. Because these are pleasing benchmarks to humans{{Citation needed}}, this is a common argument as to the utility of the Fahrenheit system; Felsius does not preserve this advantage at all. |

The title text states that the symbol he chose to represent this unit also is the average of two other symbols. Visually, it is assumed to be a combination of Celsius and Fahrenheit (a C with a crossbar), but it is actually the unrelated symbols for the {{w|Euro sign|euro}} (€) and the Greek lunate {{w|epsilon}} (ϵ). Randall's symbol has a single crossbar, like the Greek lunate epsilon, but the crossbar continues to the left, like the Euro symbol. (In this explanation and the transcript, we have used the mathematical symbol [http://graphemica.com/%E2%8B%B2 U+22F2], which may appear too large or too small depending on the font.) | The title text states that the symbol he chose to represent this unit also is the average of two other symbols.

A famous use of this fallacy is in the Bible, the {{w|Judgment_of_Solomon|Judgment of Solomon}}. The true mother of a disputed baby is discovered by proposing the "compromise" of cutting the baby in half. Perhaps Randall has a similar strategy in proposing Felsius, an absurd compromise, in order to discover the "true" temperature scale. |
