Kelvin?
Lord, yes.
That's the guy.
Of course, STP (Standard Temperature and Pressure) is defined as 273° K and 1 atmosphere of pressure. Which is why you would need to involve the Standards Committee to change it. And they would laugh...
Did you know that your mole occupies 22.4 liters of volume at STP?
And assuming you still have your mole and it hasn't found freedom yet so is still in it's 22.4 liter Big-Gulp bottle (don't tell Bloomberg) your mole will have 6.023X1023 molecules (should you desire to count them.)
If not, just go to Panera and get a Bacon, Turkey, and Avogadro sandwich. With coffee. It's a constant kind of thing. It's the least you could do to remember Amedeo..
Hot coffee is also a fine source of Brownian motion should you are driven to generate some infinite probabilities...
