I second first comment, it is NOT degrees Kelvin, just Kelvin. I am not knowlegable enough to explain why but I do know that this is true. A very common mistake.
With respect to different words for snow: I grw up in Upstate New York. Average snowfall each winter (used to be) about 4 meters. Yes 4 meters. We had "terms" for different ypes of snow: corn snow, deep powder, wet, etc.
And we also had several different types of snow shovels! Each was used in different situations, depending on the type of snow. I don't remember if each type of shovel had a different name.
Remember Cheaper by the Dozen: experts Frank Bunker Gilbreth and Lillian Moller Gilbreth.
They developed the idea (among many others) that for maximum efficiency you want different types/styles of shovels depending on what you were shovelling!
Why do I know these things??
