Square Foot Formula:
From: | To: |
Square foot calculation is a measurement of area that is widely used in construction, real estate, and interior design. It represents the area of a square with sides measuring one foot each.
The calculator uses the square foot formula:
Where:
Explanation: The calculator converts any inch measurements to decimal feet (inches ÷ 12) before performing the multiplication to get the total square footage.
Details: Accurate square footage calculations are essential for determining material quantities, estimating costs, planning layouts, and evaluating property values in construction and real estate projects.
Tips: Enter length and width measurements in feet and inches. If you have only feet or only inches, simply enter 0 in the unused field. All values must be valid (non-negative numbers, inches between 0-11).
Q1: Why calculate square footage?
A: Square footage calculation helps determine the area of a space for flooring, painting, construction materials, and property valuation.
Q2: How do I convert inches to decimal feet?
A: Divide the number of inches by 12. For example, 6 inches = 6 ÷ 12 = 0.5 feet.
Q3: Can I calculate square footage for irregular shapes?
A: This calculator is for rectangular areas. For irregular shapes, break them down into smaller rectangles, calculate each separately, then sum the results.
Q4: What's the difference between square feet and linear feet?
A: Square feet measure area (length × width), while linear feet measure length only.
Q5: How accurate should my measurements be?
A: For most projects, measuring to the nearest inch provides sufficient accuracy. For precision work, consider measuring to the nearest 1/4 or 1/8 inch.
