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 \[ \boxed{0.4} \]
