Most other countries have already switched from Fahrentheit to Celcius or have always used Celcius. In scientific circles, even in the US, only Celcius (and Kelvin) are used. |

− | [[Randall]] | + | [[Randall]] choose to name his new unit of temperature Felsius (a {{w|portmanteau}} of Fahrenheit and Celsius). |
− | + | 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 euro and the Greek lunate epsilon. | |
− | + | In doing all this, Randall has fallen into the trap of creating a new temperature scale/standard: see [[927|927: Standards]]. | |
