We reproduce the article-level, field-independent citation metric Relative Citation Ratio (RCR) using the Scopus database, and extend it beyond the biomedical field to all subject areas. We compare the RCR to the Field-Weighted Citation Impact (FWCI), also an article-level, field-normalised metric, and present the first results of correlations, distributions and application to research university benchmarking for both metrics. Our analyses demonstrate that FWCI and RCR of articles correlate with varying strengths across different areas of research. Additionally, we observe that both metrics are comparably stable across different subject areas of research. Moreover, at the level of universities, both metrics correlate strongly.
