To convert millimeters to centimeters, what is the operation performed?

• A. Divide by 10
• B. Multiply by 10
• C. Subtract 10
• D. Add 10

Answer: (B)

The conversion from millimeters to centimeters involves understanding the relationship between these two metric units. One centimeter is equal to 10 millimeters. Therefore, to convert millimeters to centimeters, you need to adjust the measurement by dividing the number of millimeters by 10. This is because you are essentially converting a larger unit (millimeters) to a smaller unit (centimeters), and since there are 10 millimeters in 1 centimeter, the operation required is division by 10. To illustrate, if you have 50 millimeters and want to find out how many centimeters this is, you would divide 50 by 10, resulting in 5 centimeters. This shows why dividing by 10 is the correct operation for this conversion. The other operations listed (such as multiplying, subtracting, or adding) do not align with the metric system's conversion principles for these units.
