Square Feet Formula:
| From: | To: |
Square feet calculation is used to determine the area of a space in square feet when measurements are provided in feet and inches. This is particularly useful in construction, real estate, and interior design for calculating floor areas, wall surfaces, and other spatial measurements.
The calculator uses the square feet formula:
Where:
Explanation: The formula converts feet and inches to total inches, calculates the area in square inches, then converts to square feet by dividing by 144.
Details: Accurate square footage calculation is essential for determining material quantities, estimating costs, planning layouts, and complying with building regulations and real estate specifications.
Tips: Enter feet as a whole number and inches as a decimal (e.g., 6.5 for 6½ inches). Ensure inches value is between 0-11.999. All values must be valid and non-negative.
Q1: Why convert to inches first?
A: Converting to inches allows for precise decimal calculations and avoids fractional foot measurements, ensuring accuracy in area calculations.
Q2: Can I use this for rectangular areas?
A: This calculator calculates square footage for a square area. For rectangles, you would need to calculate length × width separately.
Q3: How accurate is this calculation?
A: The calculation is mathematically precise when correct measurements are provided. The result is rounded to two decimal places for practical use.
Q4: What if I have measurements in different units?
A: Convert all measurements to feet and inches first before using this calculator for consistent results.
Q5: Is this suitable for irregular shapes?
A: No, this calculator is designed for square areas. Irregular shapes require more complex calculations or specialized tools.
