square inches is a measure of area, your question - as phrased - makes no sense.
How can a length be an area?
Since the units are incompatible, we can't convert in into in². Inches measures length while inches squared measures area.
divide by 144
convert 5 feet 6 inches into inches
No square unit is equal to any un-squared unit."Foot squared" is an area, but "inches" are lengths.If you want to, you can convert 4 foot squared to inches squared, but not to inches.This is how you would do it:First, you need to know the basic measurement conversion. 1 foot = 12 inches.Also, you need to know that a number squared is that number times itself.1 foot = 12 inches(1 foot) squared = (12 inches) squared = (12 inches) x (12 inches) = 144 inches squared.4 foot squared = 576 inches squared.
you cannot go from inches to centimeters squared. one inch = 2.54 cm you can go from inches squared to centimeters squared; in that case one inch square = (2.54 squared) cm = 6.45 cm squared
Impossible.
78048 inches squared
you cannot convert the volume of a cylinder from squared to cubed. the volume is always cubed. the area is squared
The conversion factor is 0.155: 20sq cm x 0.155 = 3.1 inches squared
multiply by 39.37 squared
You can't as it stands. They are measures of different things, height is one dimensional, metres squared is two dimensional. You need a width in inches; then divide both height and width by 39.4 and multiply the results. This will give a close approximation of the area in metres squared.
