to convince
'sich überzeugen' and 'überprüfen' can both mean that you look at something carefully in order to be sure. The difference is in the goal. With 'sich überzeugen von', the point is to gain certainty for yourself: you check and are sure afterward. 'überprüfen' sounds more factual and precise; you test or check whether something is correct, safe, or in order. Learners may confuse the words because both have to do with checking and verifying. In practice: if the test or check is the main focus, 'überprüfen' fits. If your own certainty is the main focus, 'sich überzeugen' fits.
