Square footage calculation is the process of determining the area of a space in square feet. It's essential for various applications including construction, flooring, painting, and real estate. This calculator specifically handles measurements provided in feet and inches.
The calculator uses the following formula:
Where:
Explanation: The formula first converts all measurements to inches, calculates the area in square inches, then converts to square feet by dividing by 144 (since 1 square foot = 144 square inches).
Details: Accurate area calculation is crucial for material estimation, cost calculation, space planning, and compliance with building regulations. It helps avoid material waste and budget overruns.
Tips: Enter measurements in feet and inches separately. For example, for 5 feet 7 inches, enter 5 in the feet field and 7 in the inches field. All values must be non-negative integers.
Q1: Why convert to inches first?
A: Converting to a common unit (inches) ensures accurate multiplication before converting to the final square footage unit.
Q2: How precise is this calculation?
A: The calculation is mathematically precise. The result is rounded to two decimal places for practical use.
Q3: Can I use this for irregular shapes?
A: No, this calculator is designed for rectangular or square areas only. Irregular shapes require different calculation methods.
Q4: What if I have measurements in decimals?
A: Convert decimal feet to feet and inches first. For example, 5.5 feet equals 5 feet 6 inches.
Q5: Why divide by 144?
A: There are 144 square inches in one square foot (12 inches × 12 inches = 144 square inches).
