Diameter to sq. ft.???

How would you convert inches in diameter to sq. ft.? Don't you need something else in the measurement?

Re: Diameter to sq. ft.???

I have two ways you can do it, by hand or using our automated calculator.

By hand:
Area = 3.14 * (diameter / 2) * (diameter / 2)

That will give you the area in square inches (assuming the diameter is inches), then you convert to square feet:
square inches / 144 = square foot

Or there is the automated calculator here:

That also will give the result in square inches (assuming the diameter is inches), so convert to square feet here:
