@Tes yeux noirs,
Fahrenheidt's scale is rather looney. Its not based on a single temp but on some dipshit guess that the orginator's own body temperature was about 96 degrees (by his scale)> the rest is dumass history.
At -40 F and C are the same . BUT C actually is dominant for science because , as equipment is almost all digital,its convenient to calibrate on the bases of tens/hundreds/ thousands -yada yada. (Try to create instruments that record digital data on 213. (something) degreed F. They would be needing recalibration daily, whereas C instruments get calibrated as they run.
THERE are actually waay more measurable degree points in C because its decimal and can be read and measured to the 1/10000 without any sweat.
As far as distances, because our instruments can easily give us both major systems (Including a few dynamic ones based on universal coorinates) its no biggy any more.
I rather feel more comfy driving in MPH or Miles distance. However, when surveying, all our maps are done in hectares, meters and tenths. Only licensed lnd surveyors still use feet and chains
This fucks up engineering constants like huge volumes of liquids, and rates of flow, but beyond that, its just an annoyance .
