Exactly. I once visited a seed bank and there was some text along the lines of “we store these seeds at -60 °C which is 3 times as cold as your typical freezer” (for Americans: a freezer typically is about -20 °C). Yeah, no, that’s not how it works. With Kelvin you can actually do math like that, because 0 K is the absence of heat zero thermal energy.
