Solution
Solution Steps
To convert millimeters to centimeters, you need to know the conversion factor between these two units. Since 1 centimeter is equal to 10 millimeters, you can convert millimeters to centimeters by dividing the number of millimeters by 10.
Step 1: Conversion Factor
To convert from millimeters (mm) to centimeters (cm), we use the conversion factor:
\[
1 \, \text{cm} = 10 \, \text{mm}
\]
Step 2: Calculation
Given the measurement of \(4 \, \text{mm}\), we convert it to centimeters using the formula:
\[
\text{cm} = \frac{\text{mm}}{10}
\]
Substituting the value:
\[
\text{cm} = \frac{4}{10} = 0.4
\]
Step 3: Rounding
The problem specifies to round the answer to the nearest tenth. The value \(0.4\) is already at one decimal place, so no further rounding is necessary.
Final Answer
The equivalent measurement for \(4 \, \text{mm}\) in centimeters is
\[
\boxed{0.4}
\]
