Abstract: This study aims to determine the correlation strength between 
impact factor (JIF), h-index and Eigenfactor (TM) of chemical engineering (CE) 
journals and its subsequent relevance in indicating the influence and prestige of 
the journals. Five-year JIFs, Eigenfactor (TM) and Article Influencer (TM) score 
for the journals are extracted from the 2008 Journal Citation Reports (R) 
whereas h-indices are determined from SCImago Journal & Country Rank and ISI 
Web of Knowledge. It is found that all the aforesaid metrics are highly 
correlated with one another (Spearman 's rho > 0.8) and it is especially true for 
broad-based CE journals. The Eigenfactor (TM) and h-index exhibit a power-law 
correlation and their combination is revealed to be the best indicator of 
prestige and impact of broad-based CE journals. Findings from this study shed 
some light on the suitability of the aforesaid metrics to complement each other 
when used as collective indicators to evaluate the influence or prestige of CE 
journals or journals of other categories.
