The Journal Impact Factor is one way of evaluating academic journals, based on the average number of citations they receive.

The Impact Factor indicates the average number of citations per paper published in a journal over a 2 year period. As the average number of citations per paper varies by academic field, it's not generally recommended for comparing journals from different disciplines (eg: biochemistry journals may have more citations on average than medical physics journals etc).

The best way to obtain the Impact Factor for a journal is to use Journal Citation Reports via Web of Science. Depending on what you want to measure/compare, it is worth exploring some of the other metrics available.
