How to Convert Inches Square to Millimeters Square
Example: How many millimeters square are equivalent to 15.46 inches square?
As;
1 inches square = 645.16 millimeters square
15.46 inches square = Y millimeters square
Assuming Y is the answer, and by criss-cross principle;
Y equals 15.46 times 645.16 over 1
(i.e.) Y = 15.46 * 645.16 / 1 = 9974.1736 millimeters square
Answer is: 9974.1736 millimeters square are equivalent to 15.46 inches square.
