**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.

**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.

## How to Convert Double Square Feet to Double Square Centimeters

*Example: How many double square centimeters are equivalent to 29.7 double square feet?*

As;

1 double square feet = 863097.48412416 double square centimeters

29.7 double square feet = Y double square centimeters

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

Y equals 29.7 times 863097.48412416 over 1

(i.e.) Y = 29.7 * 863097.48412416 / 1 = 25633995.278488 double square centimeters

Answer is: 25633995.278488 double square centimeters are equivalent to 29.7 double square feet.
