Square Foot Formula:
| From: | To: |
Square footage calculation measures the area of a two-dimensional space. It's calculated by multiplying length by width, with both measurements in the same unit (feet). This calculator allows input in feet and inches, converting inches to decimal feet for accurate calculation.
The calculator uses the formula:
Where:
Conversion: Inches are converted to decimal feet by dividing by 12 (since 1 foot = 12 inches).
Details: Square footage calculation is essential in construction, real estate, interior design, landscaping, and many DIY projects. It helps determine material quantities, property values, and space planning.
Tips: Enter length and width in feet and inches separately. The calculator will automatically convert inches to decimal feet (e.g., 6 inches = 0.5 feet). All values must be non-negative numbers.
Q1: Why include inches in the calculation?
A: Many measurements in construction and design include both feet and inches. Including both provides more precise calculations without manual conversion.
Q2: How do I measure irregularly shaped areas?
A: For irregular shapes, divide the area into regular rectangles, calculate each separately, then sum the results.
Q3: What's the difference between square feet and linear feet?
A: Square feet measure area (length × width), while linear feet measure length only. They're used for different purposes in construction and materials estimation.
Q4: Can I use this calculator for metric measurements?
A: This calculator is designed for imperial measurements (feet and inches). For metric, you would use meters and centimeters with appropriate conversion.
Q5: How accurate is the calculation?
A: The calculation is mathematically precise based on your inputs. Accuracy depends on the precision of your measurements.
