To convert \(0.0044 \text{ mg/mm}^2\) to \(\text{cg/m}^2\), we need to use the following unit conversions:

1. **Milligrams (mg) to centigrams (cg):**
   \[
   1 \text{ mg} = 0.1 \text{ cg}
   \]

2. **Square millimeters (\(\text{mm}^2\)) to square meters (\(\text{m}^2\)):**
   \[
   1 \text{ mm}^2 = 10^{-6} \text{ m}^2
   \]

So, let's perform the conversion step-by-step.

1. Convert \(0.0044 \text{ mg}\) to centigrams:
   \[
   0.0044 \text{ mg} = 0.0044 \times 0.1 \text{ cg} = 0.00044 \text{ cg}
   \]

2. Convert the area from \(\text{mm}^2\) to \(\text{m}^2\):
   \[
   1 \text{ mm}^2 = 10^{-6} \text{ m}^2
   \]

3. Therefore, \(0.0044 \text{ mg/mm}^2\) is equivalent to:
   \[
   0.00044 \text{ cg/mm}^2 = 0.00044 \text{ cg} \div 10^{-6} \text{ m}^2 = 440 \text{ cg/m}^2
   \]

So, \(0.0044 \text{ mg/mm}^2\) is equal to \(440 \text{ cg/m}^2\).
