At 40 weeks of pregnancy, the biparietal diameter is 9.9, and the femur is 7.8. Approximately how many pounds does the baby weigh?

Patient's question:

No

Doctor's answer:

Hello, according to your ultrasound report, the development indicators of the fetus are normal. There are several formulas for estimating the fetal weight:
Formula 1: Y = 260.69HC - 4973.72
Formula 2: Y = 171.48AC - 2686.60
Formula 3: Y = 747.42FL - 2232.56
Here, Y represents the fetal weight, measured in grams (g). AC is the abdominal circumference, HC is the head circumference, and FL is the femur length, measured in centimeters (cm).
