Fetal Weight Calculator - Estimate Weight and Growth Percentile

The Fetal Weight Calculator helps physicians, nurses, midwives, medical residents, students and other medical professionals quickly compute prenatal weight estimates by using one or more key measurements from a fetal sonogram (ultrasound). Weight estimates can provide helpful guidance during a mother's pregnancy and can also be used to help diagnose other potential issues.

Users provide the abdominal circumference (AC) as well as one or more of the following: biparietal diameter (BPD), femur length (FL) and head circumference (HC). The app then uses one of the standard fetal weight estimation algorithms (Shepard or Hadlock) to provide the estimate.

If the estimated fetal age is available, the app can also provide a growth percentile based on either the Hadlock growth curve or the World Health Organization growth curve.
