Answer :

To convert millimeters to centimeters, we need to use the conversion factor between these two units. Specifically, 1 centimeter is equivalent to 10 millimeters.

Given:
16.3 millimeters

We can convert millimeters to centimeters by dividing the number of millimeters by the number of millimeters per centimeter.

Step-by-step solution:

1. Write down the conversion factor:
[tex]\(1 \text{ cm} = 10 \text{ mm}\)[/tex]

2. Express the given value in millimeters:
[tex]\(16.3 \text{ mm}\)[/tex]

3. Divide the number of millimeters by the conversion factor to convert to centimeters:
[tex]\( \text{centimeters} = \frac{\text{millimeters}}{10} \)[/tex]

4. Substitute the given value:
[tex]\( \text{centimeters} = \frac{16.3 \text{ mm}}{10} \)[/tex]

5. Perform the division:
[tex]\( \text{centimeters} = 1.6300000000000001 \)[/tex]

Thus, 16.3 millimeters is equal to 1.6300000000000001 centimeters.
