How to Calculate Square Footage

Calculating the square footage of an area using imperial measurements.

(Or: I have way to much time on my hands, what can I do next!!)

How to Calculating Square Footage
Very easy to do, plug it into your calculator
for rectangle 1:
5 * 6 = 30 sq feet
for rectangle 2:
6.4 * 4 = 25.6 sq. feet 25' 6 1/8"
Perfectly acceptable for most of your calculated needs but is it right?

Rectangle 1 = 30 sq. ft. is right Rectangle 2 = 25.6 sq. ft. is wrong

In reality you should not be able to accurately multiply inches by feet on your regular calculator without converting the feet to inches. Now that should work right?

Converting to inches:
6' 4" = 76" 
4' = 48" 
76" * 48" = 3648 sq. inches * 0.00694444 (converting sq. inch to sq. ft.) = 25.333 = 25' 4"
Wow!! It works this way

How about converting the foot and inch value to decimal format. Is that the way to go?
Converting to decimal format:
6' 4" = 6.333
4' = 4.0
6.33333333 * 4.0 = 25.333 = 25' 4"
And this works too in fewer steps than converting to inches and back to feet.

And that is why our calculators require "Feet" and "Inches" to be entered in decimal format!!
