How do I convert R12 freezer to R134a?

The conversion is determined by multiplying the R12 charge value by . 75 (R12 charge x . 75 = R134a charge).

What replaces R12 freon?

There are three replacement refrigerant options for R12 systems: R134a, R401a, R401b. R134a is regarded, by manufacturers and adherents to the Montreal Protocols alike, as the best replacement refrigerant.
