How to Convert Millimeters Square to Inches Square
Example: How many inches square are equivalent to 61.66 millimeters square?
As;
1 millimeters square = 0.00155 inches square
61.66 millimeters square = Y inches square
Assuming Y is the answer, and by criss-cross principle;
Y equals 61.66 times 0.00155 over 1
(i.e.) Y = 61.66 * 0.00155 / 1 = 0.095573 inches square
Answer is: 0.095573 inches square are equivalent to 61.66 millimeters square.
