Dirt Calculation Formula:
From: | To: |
The Dirt Estimator Calculator helps you determine how much dirt you need for your landscaping or construction project by calculating the volume in cubic yards based on length, width, and depth measurements.
The calculator uses the following formula:
Where:
Explanation: The formula calculates the volume in cubic feet and converts it to cubic yards by dividing by 27.
Details: Accurate dirt estimation ensures you order the correct amount of material, avoiding costly over-ordering or project delays from under-ordering.
Tips: Measure your project area carefully in feet. For depth, consider both the desired depth and any compaction that may occur. All values must be positive numbers.
Q1: How do I measure irregularly shaped areas?
A: Break the area into smaller rectangles, calculate each separately, then sum the results.
Q2: Should I order extra dirt?
A: It's common to order 10-15% extra to account for compaction and settling.
Q3: How do I convert inches to feet for depth?
A: Divide inches by 12 (e.g., 6 inches = 0.5 feet).
Q4: What types of dirt does this calculator work for?
A: This calculates volume only. Density varies by dirt type (topsoil, fill dirt, etc.), so weight will differ.
Q5: How many wheelbarrows are in a cubic yard?
A: Approximately 14 wheelbarrow loads (at 2 cubic feet per load).
