Well, the calculation is:
"Habenero's First Law of Automotive AC Recharging" I have a pyschrometric chart for Freon, below. Using P= 90 psi ( the pressure at the low side on a typical Car AC system) and Temperature= 90 degrees farenheit ( at 4pm in New Jersey), the chart will give you the Specific Volume for Freon...uh I think...
Next, knowing the volume of the can, we can calculate how much Freon is left in the can. Having just woken up from a nap, my brain feels like what i will feel like in the year 2040, so I cant do the calculation right now..catch me at 11pm when my mind is the sharpest
