**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 Foot** (abbreviation: **ft4**): is an imperial unit and U.S. customary unit (non-SI, non-metric) 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 Feet

*Example: How many double square feet are equivalent to 72.79 double square centimeters?*

As;

1 double square centimeters = 1.1585613204537E-6 double square feet

72.79 double square centimeters = Y double square feet

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

Y equals 72.79 times 1.1585613204537E-6 over 1

(i.e.) Y = 72.79 * 1.1585613204537E-6 / 1 = 8.4331678515828E-5 double square feet

Answer is: 8.4331678515828E-5 double square feet are equivalent to 72.79 double square centimeters.
