How Does a Dirt Yardage Calculator Work?
Working of Dirt Yardage Calculator is very simple . here we are see the process of working with formula. A dirt yardage calculator takes three simple measurements:
- Length (in feet)
- Width (in feet)
- Depth (in inches)

- Where 1 cubic yard = 27 cubic feet (3ft × 3ft × 3ft).
The Dirt Yardage Formula
The formula to calculate dirt volume is:
Cubic Yards
The formula to calculate dirt volume is:
Why 324?
First, convert depth from inches to feet :
Then, divide by 27 to convert cubic feet to cubic yards:
Combining these steps simplifies to:
Step-by-Step Calculation Examples
Example 1: Garden Bed
You want to add 6 inches of topsoil to a 10 ft × 15 ft garden.
Calculation: (10×15×6)/324 = 900/324 ≈ 2.78 cubic yards
Example 2: Lawn Leveling
You need to level a 20 ft × 30 ft yard with 3 inches of fill dirt.
Calculation:
= (20×30×3)/324=1800/324 ≈5.56 cubic yards
Example 3: French Drain
Digging a trench 2 ft wide × 15 ft long × 12 inches deep for gravel.
Calculation: (2×15×12)/324 =360/324 ≈ 1.11cubic yards
