Answer

To convert \(0.5\) square centimeters (sq. cm) into square millimeters (sq. mm), we can follow these steps:

### Step-by-Step Solution:

1. **Understand the relationship between square centimeters and square millimeters**:
- We know that \(1 \, \text{sq. cm} = 100 \, \text{sq. mm}\).

2. **Set up the conversion for \(0.5 \, \text{sq. cm}\)**:
- To convert \(0.5 \, \text{sq. cm}\) into square millimeters, we can multiply \(0.5\) by the conversion factor \(100 \, \text{sq. mm/sq. cm}\).

3. **Perform the multiplication**:
- \(0.5 \, \text{sq. cm} \times 100 \, \text{sq. mm/sq. cm} = 50 \, \text{sq. mm}\).

4. **Conclusion**:
- Therefore, \(0.5 \, \text{sq. cm} = 50 \, \text{sq. mm}\).

### Final Answer:
\(0.5 \, \text{sq. cm} = 50 \, \text{sq. mm}\)
