Impact Factor vs Citations This Year to Articles in Window
सूत्र
## How Journal Impact Factor is Calculated The impact factor (IF) measures how frequently articles from a journal are cited. ### Formula **IF = Citations in Current Year to Articles Published in Prior Window / Total Articles in Window** The standard window is 2 years. A journal that published 80 articles in 2 years and received 320 citations to those articles has an IF of 4.0. ### Context - IF > 10: High impact - IF 3-10: Good impact - IF 1-3: Moderate impact - IF < 1: Lower impact
