**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 Meter** (abbreviations: **m4, or m 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 Meters

*Example: How many double square meters are equivalent to 45.21 double square centimeters?*

As;

1 double square centimeters = 1.0E-8 double square meters

45.21 double square centimeters = Y double square meters

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

Y equals 45.21 times 1.0E-8 over 1

(i.e.) Y = 45.21 * 1.0E-8 / 1 = 4.521E-7 double square meters

Answer is: 4.521E-7 double square meters are equivalent to 45.21 double square centimeters.
