doesn't work like that. There is no conversion. Its like asking "how much electricity in battery?" Without knowing what the current psi is and the volume of your system its impossible to say. under the hood someplace there is a tag that says how many pounds of coolant you need. If your system is completely empty than 16 ounces in a pound, just do the math. If its not empty get a pressure gauge and follow the directions it should have between 30-45 psi depending on outside temperature.
The total amount required is measured in PSI, which is about 35 PSI. Therefore, the amount you need is calculated by using the following formula: Required PSI = 35 PSI - Actual PSI
450 psi / 35 psi
You would need to check the PSI level. This will determine how much refrigerant you have in your system. You can get a Pressure chart on the link below. It will tell you what the PSI should be at the Current Ambient temp.

The typical suction pressure range for R-22 refrigerant is between 68-74 psi, while the discharge pressure ranges from 250-270 psi in a typical operating conditions.
The auto combustion pressure for a diesel engine is 580 psi. This is compared to the 200 psi of the gas powered engine.

Negative 30 psi should do it.
The pressure for R22 refrigerant varies depending on the temperature and phase of the refrigerant. For example, at 40°F, the pressure can be around 60 psi on the low side and 185 psi on the high side. It's important to consult a pressure-temperature chart for specific values.
A 96 Chev 1500 with a 5.0 Liter Engine calls for 32 oz of refrigerant. The recommended way to add refrigerant is by using a gauge.You can also find helpfull information on adding refrigerant to your vehicle and a chart that can guide you to the correct psi level that you need in your vehicle on www.idqusa.com.
