In this study, Descriptive correlational research design used on Johnson’s formula and Maternal Anthropometric Measurements for estimation of foetal weight and their Correlation with birth weight among Term Pregnant Mothers. Non probability purposive sampling technique with a structured interview schedule was used to collect data from the samples. Result of the 100 samples revealed that the highest knowledge score of the study was to correlate the in utero estimated fetal weight by using Johnson’s formula, Anthropometric measurements to the birth weight. It is observed that the mean correlation scores between Anthropometric measurements, Newborn Birth Weight are 3166.16±384.34. The r-value obtained was 0.20 which was statistically significant at p<0.001. The correlation between newborn birth weights with Johnson’s Estimated Fetal Weight the mean value is 3434.03, ± 411.24. The r-value obtained was 0.12 which was statistically not significant. When the birth weights were compared with the measured birth weight in different weight categories 3,500gms, Anthropometric measurements proved better than Johnson’s formula with Chi-square value 243.22 and 224.08 respectively which were significant at p<0.001. The study findings revealed that there was a significant association with age, education of mother and education of husband, the Chi-square values of which were 5.92,10.42 and 9.37 respectively at p<0.05, while other variables were not found to be statistically significant. The study findings revealed that there was a good correlation between Anthropometric Measurements and Johnson’s formula (r=0.20, p<0.001). Anthropometric Measurements formula was simple and there was better accuracy than Johnson’s formula when birth weights were compared with measured birth weights. More over ultrasound is not available in the rural areas, where as SFH ×AG formula is easy and simple to calculate.
