Pregnancy is a time of great anticipation and curiosity, and one of the most common questions expectant parents have is about the weight of their unborn baby. The estimated fetal weight (EFW) is a valuable measurement that can provide insights into the baby’s growth and development. Our Efw Fetal Weight Calculator is a simple tool designed to help you estimate your baby’s weight based on specific measurements.
Formula:
The formula used in the Efw Fetal Weight Calculator is a mathematical equation that takes into account several fetal measurements. The formula is as follows:
EFW (Estimated Fetal Weight) = 10 * Biparietal Diameter (BPD) + 2 * Head Circumference (HC) + 1.6 * Abdominal Circumference (AC) + 0.41 * Femur Length (FL) – 61.6
This formula uses four key measurements to estimate the fetal weight accurately.
How to Use:
Using the Efw Fetal Weight Calculator is a straightforward process:
- Enter the Biparietal Diameter (BPD) in millimeters.
- Input the Head Circumference (HC) in millimeters.
- Provide the Abdominal Circumference (AC) in millimeters.
- Lastly, enter the Femur Length (FL) in millimeters.
- Click the “Calculate” button.
The calculator will then process these measurements and provide you with an estimated fetal weight in grams.
Example:
Let’s say you have the following measurements:
- BPD: 90 mm
- HC: 320 mm
- AC: 280 mm
- FL: 70 mm
After entering these values into the calculator and clicking “Calculate,” you’ll get an estimated fetal weight.
