Square Feet Formula:
| From: | To: |
Square feet calculation is used to determine the area of a space by multiplying its length by its width. This measurement is essential in construction, real estate, interior design, and various other fields where area measurement is required.
The calculator uses the simple area formula:
Where:
Explanation: The calculator automatically converts inches to feet (1 inch = 1/12 feet) and then multiplies the total length by the total width to get the area in square feet.
Details: Accurate square footage calculation is crucial for determining material quantities, pricing projects, space planning, property valuation, and compliance with building codes and regulations.
Tips: Enter length and width measurements in feet and inches. The calculator will automatically convert inches to decimal feet and compute the total area. All values must be positive numbers.
Q1: How do I convert inches to feet for calculation?
A: Divide inches by 12 (1 inch = 0.0833 feet). Our calculator does this conversion automatically.
Q2: What's the difference between square feet and square meters?
A: Square feet is the imperial unit of area, while square meters is the metric unit. 1 square meter = 10.764 square feet.
Q3: When should I use this calculator?
A: Use it for calculating floor area, wall area, material requirements for flooring, painting, tiling, or any project requiring area measurements.
Q4: Can I calculate irregular shapes with this calculator?
A: No, this calculator is designed for rectangular or square areas. For irregular shapes, break them down into smaller rectangles.
Q5: How accurate are the calculations?
A: The calculations are mathematically precise based on your inputs. Always add a waste factor (typically 10-15%) for material calculations.
