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 68.82 double square meters?
As;
1 double square meters = 115.86178228926 double square feet
68.82 double square meters = Y double square feet
Assuming Y is the answer, and by criss-cross principle;
Y equals 68.82 times 115.86178228926 over 1
(i.e.) Y = 68.82 * 115.86178228926 / 1 = 7973.6078571468 double square feet
Answer is: 7973.6078571468 double square feet are equivalent to 68.82 double square meters.
