The h-index metric is an attempt to measure productivity and impact based on the citations to a group of publications. It is usually applied to a group of publications from a specific researcher, but can be used in other contexts.
The h-index is calculated from the number of papers published and the number of citations that have been made to those papers.
An h-index of 6 means that the author has published at least 6 papers that have each received at least 6 citations.
You can find your h-index using Scopus, Google Scholar and Web of Science. Your h-index might differ in these different sources because of the different literature they index. If you quote your h-index, it is good practice to say which of these sources you used to find it.
Your h-index in Scopus
Your h-index in Google Scholar
|If you have a Google Scholar profile you can see your h-index. You can set up a Google Scholar profile using Google Scholar Citations. Google Scholar tends to index a wider variety of sources, such as books and can therefore be a better choice in some disciplines.
Google Scholar Citations: Setup provides instructions for how to create you profile.

Your h-index in Web of Science
To find your h-index in Web of Science, you need to find all your articles in the database. You can do this using the author search, but you need to make sure you have correctly identified yourself and your papers, or the h-index calculation will be incorrect. Once you have identified your papers, creating a citation report on that set of papers will show you your h-index. This video shows you how to use the citation report function in Web of Science.
It is important to use a number of different metrics (not rely on just one) and to use qualitative analysis in your judgements of research outputs and researchers not just quantitative measures. Below are some of the issues you should consider when interpreting h-index values.
