This paper investigates the star formation efficiency (SFE) of blue compact galaxies (BCGs) by analyzing various indicators, including (O II), (H_α), infrared emissions, and the 1.4 GHz radio continuum. The assessment of SFE was conducted using publicly accessible data that concentrated on star formation rates (SFRs) and depletion timescales. By employing the fundamental equation, I determined the SFE in relation to its freefall time, which highlighted variations in efficiencies associated with SFR masses derived from different spectra. The results demonstrated that the highest efficiency value was observed in the analysis of the 1.4 GHz radio continuum, emphasizing the importance of studying star-forming clouds across a range of electromagnetic wavelengths to achieve a comprehensive understanding of star formation mechanisms. The study's findings indicated a peak efficiency of star formation value of approximately 0.9%, while the relative minimum obtained from (O II) was around 0.42%, aligning with the range of SFEs documented in the existing literature. Additionally, investigating the factors that influence the variability in efficiency when examining clouds in BCGs across different wave bands is crucial for deepening our comprehension of the underlying processes of star formation.
