Mean fetal weight value from multiple formulas was compared to fetal weight from single formulas. Data were collected on 975 fetuses who had estimation of fetal weight by ultrasonography within 1 week before birth. Improvement in estimation of fetal weight occurred using either the mean value of multiple formulas or the Hadlock BPD/FL/AC, in comparison to fetal volume, BPD/AC, or FL/AC. BPD/FL/AC appeared to provide the best estimate of true weight in terms of overall accuracy and in terms of not showing a trend in either overestimating or underestimating true weight.
