I have a refillable 90 gram cartridge but my c02 refill tank reads in psi, the tank is 90gram 3.20 ounces, how much psi is this?
90gram to psi

No, you weigh the empty tank before you fill it with co2 then you weigh it again after it is filled to see that you are not over the 3.2 oz it is supposed to have in it. You may have a hard time getting it to that 1800psi as that would be on a hot day. If you put your empty tank in the freezer before you fill it you may be able to get closer to a full fill. A co2 tank is not a PCP tank and should not be used as one.

that might pose a problem since this must stay in the gun till i fill it, it cannot be taken out

Guess you have to weigh the whole gun then. A cheap fish scale would do it. Although it is kind of hard to overfill one should still be careful.

Co2 runs about 750 psi at 70 degrees up to that 1800 psi around 110 degrees. Erring on the safe side... you shouldn't fill to more than 1000 psi or so IF you can even find a way to do it, as was mentioned above .

Sorry .... misread, then posted. The only GOOD way to refill co2 is to weigh it. I was thinking you were wanting to fill with air.

i have never seen co2 get around 1800psi any time, even on a 99degree day sat out in the sun. i only got to see 1100psi max. where do you read that it gets to 1800psi? even 120degree wont get it that high. i would like to see solid proof before even thinking about that number.
some people do use co2 containers and fill them with HPA, do not take anyones advise and do your own research if you play with HPA pressures in co2 vessels. i dont about about filling them attached to a gun but i wouldnt worry about filling my own if its only $3.99 at the store. weighting is what they do, dont think its any different if attached to a gun.

Air compressed is still air/gas no matter how hard you try.
CO2 compressed beyond a certain point becomes a liquid (like LPG).
Thats why CO2 cartridges gets colder as you shoot, vaporation takes energy.
As you have learned it's impossible to convert one to the other,

alot of Co2 bottles have 1800 psi burst discs, I was present when a buddy was washing the paintball paint off of them with warm water, yeah they go to 1800 psi and they will empty a sink full of water in a hurry! Co2 is very unstable with temp change, great @ 70-80. One of the best way to chill them before filling is to partially fill then drain quickly, then refill, but yes you need a scale at that point, they will fill beyond there rated weight. Just be careful
