Fetal Weight Calculator / Fetal Weight Estimation

The fetal weight calculator estimates fetal weight based on ultrasound parameters, assisting in pregnancy health management.

How to Use

1. Enter parameters such as Biparietal Diameter (BPD), Abdominal Circumference (AC), Abdominal Diameter, Femur Length (FL), etc.
2. Click "Calculate" to get fetal weight estimates using multiple formulas.

Main Formulas

• Shepard formula: Fetal weight (g) = -4973.72 + 260.69 × HC (Head Circumference)
• Formula 2: Fetal weight (g) = -2686.60 + 171.48 × AC (Abdominal Circumference)
• Formula 3: Fetal weight (g) = -2232.56 + 747.42 × FL (Femur Length)
• Formula 4: Fetal weight (g) = -2513.51 + 1049.90 × FTH (Fetal Thigh Subcutaneous Fat Thickness)
• Formula 5: Fetal weight (g) = -5168.32 + 100.97 × HC + 110.86 × AC + 143.09 × FL + 331.43 × FTH
• Formula 6: Fetal weight (g) = 900 × BPD (Biparietal Diameter) - 5200
• Formula 7: Fetal weight (g) = 2900 + 0.3 × Fundal Height × Waist Circumference
