How to use it
- Enter the length (ft), width (ft) and depth (in).
- Click the Calculate button.
- Read the cubic yards, tons (approx) and cubic feet results.
What it does – The Fill Dirt Square Feet Calculator turns the dimensions of a job site (length, width, depth) into three practical measurements: cubic feet, cubic yards, and an approximate weight in US tons.
Why it matters – Knowing cubic yards lets you order the right amount of material from suppliers, while the ton estimate helps you budget freight and labor. Over‑ordering wastes money; under‑ordering causes delays.
How to read the results – Cubic feet is the raw volume. Divide by 27 to get cubic yards (the standard unit for fill dirt). Multiply cubic yards by 1.3 to see the weight in tons.
Example – 10 ft × 12 ft × 6 in (0.5 ft) = 60 ft³ → 2.22 yd³ → ≈2.9 tons. Add a 10 % safety margin to the cubic‑yard total to cover settling and compaction.
Pro tips
- Add 10% extra for compaction and settling.
- Convert depth to feet before entering it.
- Round up to the nearest half‑yard when ordering material.
- Check that your supplier uses the same 1.3 tons per cubic yard density.
Real-life examples
- Homeowner planning a new garden bed and needs exact fill volume.
- Contractor estimating fill for a driveway ramp to avoid material shortfalls.
- Landscape designer budgeting fill dirt for a park renovation project.
Case study
Jane needed to fill a 12 ft × 8 ft × 8 in trench for a patio. Using the calculator she saw she required 2.96 yd³, about 3.9 tons. She ordered 3 yd³ plus a 10 % buffer, avoiding a costly second delivery.
