True... 1012ish, I knew that... I guess I forgot the conversion factor! It's easier to calculate.... P=NkT (the atmospheric ideal gas law... I much prefer PV=nRT, but that's ok...) P=2.46e25*1.381e-23*298 gives a P=101.23 kPa, which is 1012.3 mB. Silly me for trying to remember a silly conversion factor rather than do the calculation!

Pretty sad that I know the number density at atmospheric pressure better than I know the conversion factor... I know... but, I guess after a million scale height calculations in grad school, something had to stick with me!
