Jul 2, 2024 · To calculate the percentile, find a fetal weight percentile chart and find the intersection between the lines corresponding to the values: Estimated fetal weight 250 g; and; Gestational age 18 weeks. The closest line to the point is the 75ᵗʰ percentile, which means that the baby is heavier than 75% of all other babies the same age.

For comparison , the table below shows the 10th and 90th percentiles for EFW from a Hadlock fetal growth curve and a neonatal birth weight curve using U.S. National Center for Health Statistics data from 2011 .
Mar 3, 2020 · This calculator uses data from the NICHD Fetal Growth Study to calculate Estimated Fetal Weight (EFW) for a singleton (one) fetus between 10 weeks 0 days and 41 weeks 6 days of pregnancy. Depending on the ultrasound measurements included, the calculator can provide four estimates of EFW percentiles.
A fetal weight percentile indicates the percentage of other fetuses that weigh less than the fetus in question at the same gestational age. For example, a fetus in the 75th percentile weighs more than 75% of fetuses at the same gestational age.
