Square Feet Formula:
| From: | To: |
Square feet (SF) is a measurement of area calculated by multiplying length by width. It's commonly used in construction, real estate, and interior design to measure floor space, wall areas, and other surfaces.
The calculator uses the simple formula:
Where:
Explanation: The calculator accepts measurements in both feet and inches, converts inches to decimal feet (inches ÷ 12), then multiplies length by width to get the total square footage.
Details: Accurate square footage calculation is essential for determining material quantities, estimating costs, planning layouts, and complying with building codes and regulations.
Tips: Enter length and width measurements in feet and inches. The calculator will automatically convert inches to decimal feet and calculate the total square footage. All values must be positive numbers.
Q1: How do I convert inches to feet for the calculation?
A: Divide the number of inches by 12. For example, 6 inches equals 0.5 feet.
Q2: Can I calculate square feet for irregular shapes?
A: This calculator is designed for rectangular areas. For irregular shapes, break the area into smaller rectangles, calculate each separately, then sum the results.
Q3: How accurate should my measurements be?
A: For most purposes, measuring to the nearest inch is sufficient. For precise calculations (like material ordering), measure to the nearest 1/4 inch.
Q4: Does this work for three-dimensional calculations?
A: No, this calculates area (square feet). For volume (cubic feet), you would need to multiply by height as well.
Q5: How do I calculate square feet from metric measurements?
A: First convert meters to feet (1 meter = 3.28084 feet), then use the calculator. Or convert square meters to square feet (1 m² = 10.7639 ft²).
