Background: The key predictor of the outcome of labour, as well as of perinatal illness, mortality, and maternal morbidity, is the weight of the foetus as determined by ultrasonography. The manner of delivery can be chosen by the obstetrician using an ultrasound estimate of the foetal weight at term. Aim: This study was conducted to correlate the ultrasonographic estimated fetal weight at term with actual birth weight in patients attending the medical college hospital. Materials and Methods: In collaboration with the radiology department, the study was carried out at OBG department. The time frame for this study's retrospective cross-sectional design was from February 2019 to November 2021. 300 pregnant women were selected in the study. Results: The estimated foetal weight determined by ultrasonography and the actual birth weight correlated favourably. 88% of predicted weights were within ten percent of actual birth weight on average. Conclusion: The weight of the foetus at ultrasonography and the actual birth weight were closely correlated. Making decisions in the delivery room requires the use of this crucial tool.
