Square Footage 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 areas, wall surfaces, and other two-dimensional spaces.
The calculator uses the basic area formula:
Where:
Explanation: The calculator automatically converts inches and centimeters to feet before performing the calculation, ensuring accurate results regardless of the input unit.
Details: Accurate square footage calculation is essential for determining material quantities, estimating costs, planning space utilization, and property valuation in real estate transactions.
Tips: Enter length and width measurements, select the appropriate unit for each (inches, centimeters, or feet). All values must be positive numbers. The calculator will automatically convert to feet and compute the square footage.
Q1: How do I convert inches to feet?
A: Divide the number of inches by 12. For example, 24 inches = 24/12 = 2 feet.
Q2: How do I convert centimeters to feet?
A: Divide the number of centimeters by 30.48. For example, 152.4 cm = 152.4/30.48 = 5 feet.
Q3: 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.
Q4: Can I calculate irregular shapes with this calculator?
A: This calculator is designed for rectangular areas. For irregular shapes, you may need to break the area into multiple rectangles and sum their square footages.
Q5: Why is square footage important in real estate?
A: Square footage is a key factor in property valuation, pricing, and comparison between properties. It helps determine the usable space and affects property taxes.
