Square Footage Formula:
| From: | To: |
Square footage calculation measures the area of a space in square feet. It's essential for various applications including construction, real estate, flooring installation, and landscaping projects.
The calculator uses the formula:
Where:
Explanation: The calculator converts inches to decimal feet (by dividing by 12) and adds them to the whole feet measurements before multiplying length by width.
Details: Accurate square footage calculations are crucial for determining material quantities, project costing, space planning, and property valuation. Even small measurement errors can lead to significant cost overruns or material shortages.
Tips: Enter whole feet and additional inches separately for both length and width. Ensure inch values are between 0-11. For irregularly shaped areas, divide into rectangles, calculate each separately, then sum the results.
Q1: Why measure in both feet and inches?
A: Many construction and real estate measurements are taken in feet and inches. This format allows for precise input without needing to convert to decimal feet manually.
Q2: How accurate is this calculation?
A: The calculation is mathematically precise. Accuracy depends on the precision of your measurements. Always measure twice for critical applications.
Q3: Can I calculate square footage for circular areas?
A: This calculator is designed for rectangular areas. For circles, use the formula: Area = π × radius² (with radius in feet).
Q4: How do I calculate square yards from square feet?
A: Divide the square footage by 9. There are 9 square feet in 1 square yard.
Q5: What if I have measurements in meters?
A: Convert meters to feet first (1 meter = 3.28084 feet), then use the calculator, or use a metric area calculator instead.
