this momentary, light affliction is producing for us an eternal burden of glory

Paul speaks of his sufferings and the glory that God will give him as if they were objects that can be weighed. He uses irony to call affliction, which people usually think of as if it were a heavy burden, a light burden and glory, which people usually think of as relief from suffering, as if it were a heavy burden. Through this metaphor he is saying that the glory to come will be much greater than the affliction. (See: rc://en/ta/man/jit/figs-metaphor and rc://en/ta/man/jit/figs-irony)

that exceeds all measurement

The glory that Paul will experience is so great that no one can measure it. The abstract noun "measurement" can be translated as the verb "measure." Alternate translation: "that no one can measure" (See: rc://en/ta/man/jit/figs-metaphor and rc://en/ta/man/jit/figs-abstractnouns)
