Abdominal Circumference to Head Circumference Ratio Calculator

Formula

To calculate the abdominal circumference to head circumference ratio:

\[ R = \frac{AC}{HC} \]

Where:

\(R\) is the ratio of abdominal circumference to head circumference
\(AC\) is the abdominal circumference in centimeters
\(HC\) is the head circumference in centimeters

What is the Abdominal Circumference to Head Circumference Ratio?

The abdominal circumference to head circumference ratio is a measurement used in various medical and health assessments. It compares the size of the abdomen to the size of the head, providing insights into growth patterns, nutritional status, and potential health issues. This ratio is particularly useful in prenatal and pediatric evaluations, helping healthcare providers monitor and assess the development of fetuses and infants.

Example Calculation 1

Let's assume the following values:

Abdominal Circumference (\(AC\)) = 30 cm
Head Circumference (\(HC\)) = 35 cm

Using the formula:

\[ R = \frac{30}{35} \approx 0.86 \]

The ratio is approximately 0.86.

Example Calculation 2

Let's assume the following values:

Abdominal Circumference (\(AC\)) = 25 cm
Head Circumference (\(HC\)) = 32 cm

Using the formula:

\[ R = \frac{25}{32} \approx 0.78 \]

The ratio is approximately 0.78.
