1 inch =25.4mm. That is right.
But when squaring, you have to square both the units _and_ the numbers, so
1 inch = 25.4 mm
(1 inch)^ = (25.4mm)^2
(1^2) inch^2 = (25.4^2) mm^2
1 in^2 = 645.16 mm^2
Or think of it this way:
Draw a 3-inch line. That's 3 inches.
Now make a square from it with 3 inches on each side. How many square inches is that?
