**Definitions:**

**Double Square Centimeter** (abbreviations: **cm4, or cm 4**): is the SI derived unit of area moment of inertia, a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis.

**Double Square Millimeter** (abbreviations: **mm4, or mm 4**): is the SI derived unit of area moment of inertia, a geometrical property of an area which reflects how its points are distributed with regard to an arbitrary axis.

## How to Convert Double Square Centimeters to Double Square Millimeters

*Example: How many double square millimeters are equivalent to 9.82 double square centimeters?*

As;

1 double square centimeters = 10000 double square millimeters

9.82 double square centimeters = Y double square millimeters

Assuming Y is the answer, and by criss-cross principle;

Y equals 9.82 times 10000 over 1

(i.e.) Y = 9.82 * 10000 / 1 = 98200 double square millimeters

Answer is: 98200 double square millimeters are equivalent to 9.82 double square centimeters.
