Conversion Formula

The formula to convert feet to square feet is simple: you multiply the length value in feet by itself. This works because square footage measures area, which is a two-dimensional measurement. For example, if you have 15 ft, then the calculation is 15 ft * 15 ft = 225 sq ft. Each foot length is multiplied by the same length to get the area in square feet, reflecting how much space the object covers.

Conversion Example

• Convert 10 ft to square:
  • Step 1: Take the value in feet, which is 10.
  • Step 2: Multiply 10 by 10, because area is length times width.
  • Step 3: 10 * 10 = 100.
  • Answer: 10 ft equals 100 square feet.
• Convert 20 ft to square:
  • Step 1: Length is 20 feet.
  • Step 2: Multiply 20 by 20.
  • Step 3: 20 * 20 = 400.
  • Answer: 20 ft equals 400 square feet.
• Convert 5 ft to square:
  • Step 1: Length is 5 feet.
  • Step 2: Multiply 5 by 5.
  • Step 3: 5 * 5 = 25.
  • Answer: 5 ft equals 25 square feet.

Conversion Definitions

ft

Feet (ft) is a unit of linear measurement used mainly in the United States, equal to 12 inches, representing length or distance in a straight line, such as height, width, or length of objects.

square

Square refers to a measurement of area, indicating the size of a surface, obtained by multiplying a length by itself, such as square feet, square meters, or square inches, measuring the amount of space covered or enclosed.

Conversion FAQs

How do I convert 15 ft to square feet manually?

To convert 15 ft to square feet, multiply 15 by 15 because area in square feet is the product of length times width, assuming a square shape. The calculation is 15 * 15, which equals 225 square feet.

Can I convert 15 ft to square meters directly?

No, converting feet to square meters requires first calculating square feet and then applying the conversion factor. One square foot equals approximately 0.0929 square meters, so you’d multiply 225 sq ft by 0.0929 to get square meters.

What is the area in square feet of a rectangular space measuring 15 ft by 10 ft?

Multiply the length (15 ft) by the width (10 ft): 15 * 10 = 150 square feet. This gives the total area of that rectangular space.

Why does multiplying 15 by itself give the square footage?

Because area measures two-dimensional space, multiplying length by width (both in feet) provides the total surface area in square feet. For square shapes, length and width are equal, so multiplying a single measurement by itself works.
