Hi Rod. They are two different tools. I use my calipers for a bit of everthing when precision is not the most critical(+/-.001). A decent caliper will allow 4 way measurment 3 are pretty useful. OD ID and depth. A micrometer is strickly OD but with a little practice it is not to hard to split .001 10 ways or .0001 accuracy.
I do very highly recomend getting a digital/ electronic caliper so you get direct readings in inches or metric at a push of a button. I have made very expensive mistakes with simple misreads on dials and mics,it does happen to the best tool makers. I would spend a few bucks and get a high quality caliper, they should be accurate over their entire range. If I had to pick a best/affordable, I would go for a 6" mitutoyo digimatic. The perfect high end match for a porsche is a Mahr,made in Germany and very accurate with a great feel. The mits should be a little more or less than $100 and will last many lifetimes.
