20 Feet to Square – Easy Conversion Explained

The conversion of 20 feet to square equals 400 square feet.

Since 1 foot is a linear measurement, to find the area in square feet from feet, you multiply the length by itself. Therefore, 20 feet times 20 feet gives 400 square feet, which is the area covered if you think of a square that is 20 feet on each side.

Area Calculation for 20 Feet

To convert feet to square feet, you need to square the length measurement. This means multiplying the number of feet by itself. For example, 20 feet multiplied by 20 feet results in 400 square feet, representing the area of a square with sides of 20 feet.

Conversion Formula

The formula to convert feet to square feet is simple: area in square feet = length in feet * length in feet. It works because area is a two-dimensional measurement, so when you have a linear measurement in feet, you multiply it by itself to get the total area.

For example, if you have 20 feet, then 20 multiplied by 20 equals 400, which gives you 400 square feet. This calculation assumes a square shape, but for rectangles, you multiply length by width.

Conversion Example

• Convert 10 feet to square feet:
  • Multiply 10 by 10.
  • 10 * 10 = 100.
  • Result is 100 square feet.
• Convert 5 feet:
  • Multiply 5 by 5.
  • 5 * 5 = 25.
  • So, 25 square feet.
• Convert 15 feet:
  • 15 times 15.
  • 15 * 15 = 225.
  • Resulting in 225 square feet.
• Convert 8 feet:
  • 8 multiplied by 8.
  • 8 * 8 = 64.
  • Area is 64 square feet.
• Convert 12 feet:
  • 12 times 12.
  • 12 * 12 = 144.
  • Gives 144 square feet.

Conversion Definitions

Feet

Feet are linear measurement units used mainly in the US customary system, equal to 12 inches, and are used to measure length or distance in construction, real estate, and daily measurements for smaller spaces or objects.

Square

Square, in measurement terms, refers to an area unit obtained by multiplying a length measurement by itself, representing the space covered within a square shape with sides of that length, such as square feet or square meters.

Conversion FAQs

What does converting 20 feet to square feet mean?

This means calculating the area of a square that has each side measuring 20 feet, which results in 400 square feet. It’s a way to understand how much surface area is covered when measuring length in feet.

Can I convert 20 feet to acres directly?

Not directly, because acres measure land area, and to convert from square feet to acres, you divide the square feet by 43,560. So, 400 square feet equals approximately 0.0092 acres.

How accurate is the conversion for irregular shapes?

The conversion formula applies for regular shapes like squares or rectangles. For irregular shapes, you need to divide the shape into smaller regular parts, calculate each area, and sum them up for accuracy.

Is the conversion the same if I change the unit to yards?

No, converting feet to yards involves dividing by 3 because 1 yard equals 3 feet. To get square yards, you would convert linear feet to yards then square that number.

Why do I need to square the feet measurement when converting to square feet?

Because area measures two dimensions, so multiplying the length by itself accounts for both dimensions, giving the total surface in square units, instead of just linear measurement.
