Cubic Yards Formula:
From: | To: |
The cubic yard calculation determines the volume of stone or other materials needed for a project. It's essential for ordering the correct amount of materials and estimating costs accurately.
The calculator uses the following equation:
Where:
Explanation: The formula converts all measurements to feet (depth from inches to feet by dividing by 12), calculates cubic feet, then converts to cubic yards by dividing by 27.
Details: Accurate cubic yard calculation helps prevent over-ordering or under-ordering materials, ensures proper budgeting, and helps with project planning and execution.
Tips: Enter length and width in feet, depth in inches. All values must be positive numbers. For irregular areas, divide into rectangular sections and calculate separately.
Q1: Why divide by 27 in the formula?
A: There are 27 cubic feet in 1 cubic yard (3 feet × 3 feet × 3 feet = 27 cubic feet).
Q2: How do I measure irregular areas?
A: Break the area into smaller rectangles, calculate each separately, then sum the results.
Q3: Should I add extra to my order?
A: It's common to add 10-15% to account for compaction, settling, or measurement errors.
Q4: How does depth affect the calculation?
A: Depth is the most sensitive variable - small changes in depth significantly impact the total cubic yards needed.
Q5: Can this be used for other materials?
A: Yes, this calculation works for any bulk material (mulch, gravel, soil) when you need to determine volume in cubic yards.
