Double Square Millimeter (abbreviations: mm4, or mm 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 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 Millimeters to Double Square Centimeters
Example: How many double square centimeters are equivalent to 72.1 double square millimeters?
As;
1 double square millimeters = 0.0001 double square centimeters
72.1 double square millimeters = Y double square centimeters
Assuming Y is the answer, and by criss-cross principle;
Y equals 72.1 times 0.0001 over 1
(i.e.) Y = 72.1 * 0.0001 / 1 = 0.00721 double square centimeters
Answer is: 0.00721 double square centimeters are equivalent to 72.1 double square millimeters.
