**Definitions:**

**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.

**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 Meters to Double Square Feet

*Example: How many double square feet are equivalent to 9.92 double square meters?*

As;

1 double square meters = 115.86178228926 double square feet

9.92 double square meters = Y double square feet

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

Y equals 9.92 times 115.86178228926 over 1

(i.e.) Y = 9.92 * 115.86178228926 / 1 = 1149.3488803094 double square feet

Answer is: 1149.3488803094 double square feet are equivalent to 9.92 double square meters.
