Square inches and square feet - Imperial units of area

We use different units to measure area quantities. In the imperial system of units, the most commonly used to measure area are the square inches (in2) and the square feet (ft2).

There's a direct correlation between these two units, and it's given by:

• 1 ft2 = 144 in2

  or

• 1 in2 = 1/144 ft2 = 0.00694444 ft2

This way, you can express the same property (area) with another unit of measurement. Even though they'll be numerically different, both represent the same area.

For instance, if a given region has an area of 432 in2, and we apply the conversion factor expressed above, we can say that this is equivalent to 3 ft2.

How to convert square inches to square feet

To calculate any surface area, we use linear or one-dimensional measures and go on from there. In this particular case, we'll be referring to inches and feet, which are imperial units to measure distances.

The appropriate conversion factor between these two is 12 inches equal to 1 foot:

12 in=1 ft12\text { in} = 1\text{ ft}12 in=1 ft

By multiplying this linear conversion factor by itself, we can go from one-dimensional quantities to two-dimensional or area values:

12 in×12 in=1 ft×1 ft{12\text{ in}} \times {12\text{ in}} = 1\text{ ft} \times 1\text{ ft}12 in×12 in=1 ft×1 ft

144 in2=1 ft2144 \text { in}^2 = 1 \text{ ft}^2144 in2=1 ft2

The above corresponds to the conversion factor to go from areas in square inches to square feet or the other way around.

Finally, the next step is to apply this factor to swap between square inches and square feet.

For example, to convert an area of 36 in236\text { in}^236 in2 to  ft2\text{ ft}^2 ft2, we simply divide 36 in236\text { in}^236 in2 by 144 in2144\text { in}^2144 in2:

36 in2×(1 ft2/144 in2)=0.25 ft236\text { in}^2 \times (1\text { ft}^2 / 144 \text { in}^2) = 0.25 \text { ft}^236 in2×(1 ft2/144 in2)=0.25 ft2
