Area Calculation Formula:
From: | To: |
Square foot calculation converts linear measurements in inches to area measurements in square feet. This is essential for various applications including flooring, painting, construction, and material estimation.
The calculator uses the conversion formula:
Where:
Explanation: Since 1 foot equals 12 inches, 1 square foot equals 12 × 12 = 144 square inches. Dividing the area in square inches by 144 converts it to square feet.
Details: Accurate area calculation is crucial for material estimation, cost calculation, project planning, and ensuring proper coverage in construction and renovation projects.
Tips: Enter both length and width measurements in inches. Ensure measurements are accurate and in the same unit. The calculator will provide the area in square feet.
Q1: Why divide by 144?
A: Because 1 square foot contains 144 square inches (12 inches × 12 inches).
Q2: Can I use this for irregular shapes?
A: This formula works for rectangles and squares. For irregular shapes, break them down into smaller rectangular sections and sum the areas.
Q3: What about measurements in feet and inches?
A: Convert all measurements to inches first, or use a dedicated feet-and-inches calculator.
Q4: How accurate should my measurements be?
A: For most projects, measurements to the nearest 1/4 inch are sufficient. For precision work, measure to 1/16 inch.
Q5: Can this be used for circular areas?
A: No, this formula is for rectangular areas. For circles, use: Area = π × radius² (in inches) ÷ 144.
