From: | To: |
Square feet calculation is a measurement of area commonly used in construction, real estate, and interior design. It represents the area of a two-dimensional space measured in feet.
The calculator uses the square feet formula:
Where:
Explanation: The calculator first converts any inches input to decimal feet (inches ÷ 12), then multiplies length by width to calculate the total square footage.
Details: Accurate square footage calculation is essential for determining material quantities, pricing projects, space planning, and property valuation.
Tips: Enter length and width in feet and inches. The calculator automatically converts inches to decimal feet. All values must be non-negative numbers.
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 feet for irregular shapes?
A: This calculator is designed for rectangular areas. For irregular shapes, break the area into rectangular sections and sum their square footages.
Q3: How accurate should my measurements be?
A: For most applications, measuring to the nearest inch provides sufficient accuracy. For precise work, consider measuring to the nearest 1/4 or 1/8 inch.
Q4: What's the difference between square feet and linear feet?
A: Square feet measure area (length × width), while linear feet measure length in a straight line.
Q5: How do I convert square feet to other units?
A: 1 square foot = 144 square inches, 1 square yard = 9 square feet, 1 square meter ≈ 10.764 square feet.
