This question as asked can not be answered.
1psi = 0.068 atm. So to convert 30 psi using dimensional analysis... 30 psi x 0.068 atm/1 psi = 2.04 atm
The system will take 30 ounces of R134a freon.............
Aprox 30 oz.
30 psi
10 psi minimum, 30 psi would be better.10 psi minimum, 30 psi would be better.
I just had 2 pounds of Freon added to my central A/C and was charged $30 a pound.

about 25-30 psi....
30kPa= 4.35 psi
30 psi all around
to answer your question they are about 30 bucks a can but you can not do the work your self because no and days they have a recaptor tecnique to catch the release of the extra freon left in the system
30-40 psi
