Methods - This was a prospective comparative conducted at Umaid Hospital, Dr. SN medical college Jodhpur to compare accuracy of fetal weight estimation by clinical method and USG method at term pregnancy and compared with actual birth weight in 100 patients. In clinical method Johnson's formula was used. Results-both clinical methods and sonographic method show good correlation with actual birth weight in all birth weight ranges (r= 0.829 and r= 0.904, p-value for both <0.05) except in extreme of birth weight. Both methods correlated well at birth weight range 2.5 kg to 3.5 kg. In extreme of weight USG is better than clinical method. Conclusion: Our study shows that Johnson's formula effectively estimates birth weight and so in low resources settings where USG facility is not easily available, clinical estimation of fetal weight can gives an idea of fetal weight and so helps in deciding optimal mode of delivery.
