How to Convert Millimeters Square to Feet Square
Example: How many feet square are equivalent to 63.58 millimeters square?
As;
1 millimeters square = 1.1E-5 feet square
63.58 millimeters square = Y feet square
Assuming Y is the answer, and by criss-cross principle;
Y equals 63.58 times 1.1E-5 over 1
(i.e.) Y = 63.58 * 1.1E-5 / 1 = 0.00069938 feet square
Answer is: 0.00069938 feet square are equivalent to 63.58 millimeters square.
