Hello! I'm having trouble to understand the difference between unitless and dimensionless. Many people on the internet says different things, so I need someone to really confirm me this, because I'm turning crazy kkkk.
So, let's start with temperature. I say T =400 K.
1) What is 400? Is it the unit and is that what the "unit" in unitless stands for?
2) What is Kelvin? I know it is the unit of measure, but is that what the unit in unitless stands for?
3) Also, temperature is a scalar quantity because it is not a vector. Is t classification of a vector/scalar quantity a third classification, or is "scalar" the same as dimensionless or unitless?
