its easier if it becomes a second language rather than converting. In science we use the cgs system mostly, in geology we usecgs, English, AND mining measure. (chains n radians rather than feet and degrees). We also use Kelvin a lot but that I need to convert cause its for really hot earth core recipes of iron silica melts.
I go back and foprth in cgs an English as if when you can think in nother language.
If youre not in chem /physics/geophysics/ or ecology/microbio You have no need to take up a temperature language or dealing back and forth in mass v weight ,or mg/L v ppm or degrees v % of a circle in radians
