Dirt Volume Formula:
Definition: This calculator estimates the volume of dirt in cubic yards based on length, width, and depth measurements in feet.
Purpose: It helps landscapers, gardeners, and construction professionals determine how much dirt is needed or removed for various projects.
The calculator uses the formula:
Where:
Explanation: The length, width, and depth are multiplied to get cubic feet, then divided by 27 to convert to cubic yards.
Details: Accurate dirt volume estimation ensures proper project planning, cost-effective material purchasing, and efficient waste disposal.
Tips: Enter the length, width, and depth in feet. All values must be > 0. For irregular areas, divide into rectangular sections and calculate separately.
Q1: Why divide by 27?
A: There are 27 cubic feet in 1 cubic yard (3 feet × 3 feet × 3 feet).
Q2: How do I measure depth for uneven areas?
A: Take multiple depth measurements and use the average, or calculate sections separately.
Q3: Does this account for compaction?
A: No, for compacted dirt, you may need to add 10-20% to your calculated volume.
Q4: What's the difference between topsoil and fill dirt?
A: Topsoil is nutrient-rich for planting (about 1.25 tons/cu yd), while fill dirt is subsoil (about 1.5 tons/cu yd).
Q5: How do I convert cubic yards to tons?
A: Multiply cubic yards by 1.25-1.5 depending on dirt type and moisture content.
