Square Feet Formula:
| From: | To: |
Square feet calculation is a fundamental measurement used to determine the area of a two-dimensional space. It's commonly used in construction, real estate, interior design, and landscaping to measure floor space, wall areas, and property sizes.
The calculator uses the simple area formula:
Where:
Explanation: The formula multiplies the length by the width to calculate the total area in square feet. This works for any rectangular or square space.
Details: Accurate area calculation is essential for determining material quantities (flooring, paint, carpet), space planning, property valuation, and compliance with building codes and regulations.
Tips: Enter both length and width measurements in feet. Ensure measurements are accurate and in the same unit (feet). The calculator will automatically compute the area in square feet.
Q1: Can I use this calculator for irregular shapes?
A: This calculator is designed for rectangular areas. For irregular shapes, you may need to break the area into multiple rectangles, calculate each separately, then sum the results.
Q2: How do I convert square feet to other units?
A: 1 square foot = 144 square inches, 0.092903 square meters, or 0.0000229568 acres. Multiply your square footage by the appropriate conversion factor.
Q3: Should I measure in feet or convert from inches?
A: For accuracy, measure directly in feet when possible. If measuring in inches, divide by 12 to convert to feet before calculation (e.g., 18 inches = 1.5 feet).
Q4: How accurate should my measurements be?
A: For most applications, measuring to the nearest 1/4 foot (3 inches) is sufficient. For precise work like tile installation, measure to the nearest 1/12 foot (1 inch).
Q5: Does this work for three-dimensional calculations?
A: No, this calculates area (2D). For volume calculations (cubic feet), you would need to multiply area by height/depth.
