Similarly, to convert square millimeters into square centimeters we use the reverse
operation; that is, we divide the square millimeters by a factor of 100. Thus,
200 square millimeters = 200 ÷ 100 = 2 square centimeters.
To convert volume units within the Metric or SI system, use the relationships given
in Table 5.9. For example, to convert cubic centimeters into cubic millimeters, the
table shows that we multiply the number of cubic centimeters by a factor of 1000.
Thus, for instance, to convert two cubic centimeters into cubic millimeters:
2 cubic centimeters = 2 × 1000 = 2000 cubic millimeters
Similarly, to convert cubic millimeters into cubic centimeters we use the reverse
operation; that is, we divide the cubic millimeters by a factor of 1000. Thus,
2000 cubic millimeters = 2000 ÷ 1000 = 2 cubic centimeters.
To convert mass units within the Metric or SI system, use the relationships given
in Table 5.10. For example, to convert centigrams into milligrams, the table shows
that we multiply the number of centigrams by a factor of 10. Thus, for instance, to
convert two centigrams into milligrams:
2 centigrams = 2 × 10 = 20 milligrams
