PMBOK 4th edition page 150 is clear about what are parametric estimates, however the word metrics appears also in several materials regarding project management, this is a subtle question but for some reason I relate these 2 terms, however I would like to know if somebody understands the real difference between PARAMETRIC ESTIMATING AND METICS, I relate "metrics" more to the result of measurements and "parametric estimating" more to the process itself of calculating data with information given, I would very much appreciate if someone would like to comment on this. -I am only learning to take the PMP exam so pls excuse since surely engineers might think question is not worthwhile, I therefore apologize but formus are precisely to help each other so I thought I would give it a try. thank you very much for the attention you may give to my doubt.

I believe you have it correct already. Parametric estimating is an action whereas metrics are measurements or outcomes. Thus, parametric estimating would not only use metrics as input (historical data) but also produce a new set of metrics (measurements or outcomes) after compared to a set of parameters.
