Square Feet Formula:
| From: | To: |
Square footage calculation is the process of determining the area of a space in square feet. It's commonly used in construction, real estate, and interior design to measure floor space, wall areas, and other surfaces.
The calculator uses the square footage formula:
Where:
Explanation: The calculator converts inches to decimal feet (1 inch = 1/12 feet) before performing the multiplication to get the total square footage.
Details: Accurate square footage calculation is essential for determining material quantities for flooring, painting, or tiling projects, calculating property values in real estate, and planning space utilization in interior design.
Tips: Enter length and width in feet and inches separately. The calculator will automatically convert inches to decimal feet and calculate the total square footage. All values must be valid (non-negative numbers, inches between 0-11).
Q1: 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.
Q2: Can I calculate square footage for irregular shapes?
A: This calculator is designed for rectangular areas. For irregular shapes, you would need to break the area into smaller rectangles, calculate each separately, and sum the results.
Q3: Why is square footage important in real estate?
A: Square footage is a key factor in determining property value, with price often calculated per square foot. It also helps buyers understand the actual size and layout of a property.
Q4: How accurate should my measurements be?
A: For most purposes, measuring to the nearest inch is sufficient. For precise construction or high-value projects, more precise measurements may be needed.
Q5: Can this calculator be used for metric measurements?
A: This calculator is designed for imperial measurements (feet and inches). For metric calculations, you would need a different calculator that works with meters and centimeters.
