Cubic Yards Formula:
| From: | To: |
The square feet to cubic yards conversion calculates the volume of material needed when you know the area in square feet and the depth in feet. This is commonly used in construction, landscaping, and materials estimation.
The calculator uses the formula:
Where:
Explanation: The formula converts square feet at a given depth to cubic yards by multiplying the area by the depth, then dividing by 27 (since 1 cubic yard = 27 cubic feet).
Details: Accurate cubic yard calculation is essential for ordering the correct amount of materials like concrete, soil, mulch, or gravel, helping to avoid project delays and cost overruns.
Tips: Enter the area in square feet and the depth in feet. Both values must be positive numbers. The calculator will provide the volume in cubic yards.
Q1: Why divide by 27 in the formula?
A: Because there are 27 cubic feet in 1 cubic yard (3 feet × 3 feet × 3 feet = 27 cubic feet).
Q2: Can I use this for irregular shapes?
A: This calculator works best for rectangular or regularly shaped areas. For irregular shapes, break the area into regular sections and calculate each separately.
Q3: What if my depth is in inches instead of feet?
A: Convert inches to feet first (divide by 12) before using the calculator.
Q4: How accurate is this calculation?
A: The calculation is mathematically precise. Accuracy depends on your measurements of the area and depth.
Q5: Should I add extra for compaction or waste?
A: For materials that compact or have waste, it's recommended to add 10-20% to your calculated amount.
