Square Footage Formula:
| From: | To: |
Square footage calculation measures the area of a two-dimensional space. It's calculated by multiplying the length by the width of a space, typically measured in feet. This measurement is essential in construction, real estate, and interior design.
The calculator uses the square footage formula:
Where:
Explanation: The calculator converts any inches input to decimal feet (inches ÷ 12) before performing the multiplication to get the total square footage.
Details: Accurate square footage calculation is crucial for determining material quantities, property valuation, space planning, 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 (1 inch = 0.0833 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 use this calculator for irregularly shaped rooms?
A: This calculator is designed for rectangular or square areas. For irregular shapes, you may need to divide the space into multiple rectangles, calculate each separately, then sum the results.
Q3: How accurate should my measurements be?
A: For most purposes, measuring to the nearest inch is sufficient. For precise calculations (like flooring materials), consider measuring to the nearest 1/4 inch.
Q4: Does this calculator account for waste factor?
A: No, this calculator provides the exact area measurement. For material estimation, you should add a waste factor (typically 5-10%) to your calculated square footage.
Q5: Can I calculate square footage from metric measurements?
A: This calculator is designed for feet and inches. For metric measurements, convert centimeters to meters first (1 meter = 100 cm), then multiply length × width to get square meters.
