One centimeter equals ten millimeters; therefore, 1 cm = 10 mm. It indicates that to calculate the number of millimeters per centimeter, you will need to multiply the centimeter measurement by 10, starting with 1.

Even though the millimeter and the centimeter are derived from the fundamental unit known as the meter, the millimeter is the smaller of the two. Therefore, multiplying the initial value is required whenever you convert a bigger metric unit to a smaller metric unit of any kind.

Example: 47.83 cm x 10 = 478.3 mm

The width of the table in the problem is 478.3 millimeters.
