Due to my current role I have to help grade journals, so as a bit of a test, I had a look at the h index and SJR value of journals roughly in my area (areas?) of research.I used SJR and Google Scholar metrics. They calculate h value differently (the latter has an h5 for 5 years rating) but it was interesting to compare. Individual conferences can score highly but are hard to compare to journals as they appear to be often rated individually rather than as a series. SIGGRAPH is one of the exceptions (Google, SCIMAGOJR) but compare to CHI (google, SCIMAGOJR?)

SJR (SCImago Journal Rank) indicator: It expresses the average number of weighted citations received in the selected year by the documents published in the selected journal in the three previous years, –i.e. weighted citations received in year X to documents published in the journal in years X-1, X-2 and X-3. See detailed description of SJR .

H Index: The h index expresses the journal’s number of articles (h) that have received at least h citations. It quantifies both journal scientific productivity and scientific impact and it is also applicable to scientists, countries, etc. (see H-index wikipedia definition).
