What it does – The Fill Dirt Calculator turns the dimensions of a trench, pad, or garden bed into three practical measures: cubic yards, cubic feet, and an estimated weight in tons. You enter length and width in feet and depth in inches; the tool converts depth to feet, multiplies the three dimensions to get volume, then divides by 27 to show cubic yards. It multiplies cubic yards by 1.3 to give a rough tonnage, which is the industry standard for compacted fill dirt. Why it matters – Knowing cubic yards helps you order the right amount of material and avoid costly over‑orders, while tons let you compare freight quotes. How to read it – Cubic yards is the primary order unit, cubic feet helps visualize space, and tons estimates the load weight for delivery planning.
Pro tips
- Add 5‑10% extra volume for compaction and spillage.
- Round up to the nearest whole cubic yard when ordering.
- Compare supplier tonnage rates using the ton estimate.
- Double‑check depth measurement; an inch error can change volume noticeably.
Real-life examples
- A homeowner preparing a 12‑ft by 8‑ft patio base 6 in deep.
- A contractor estimating fill for a 30‑ft driveway extension 8 in deep.
- A landscaper needing soil for a raised garden bed 4 ft by 10 ft at 12 in depth.
Case study
John needed a 10 × 6 ft patio pad 5 in deep. Using the calculator he saw he required 0.74 cubic yards (≈1 ton). He ordered 1 cubic yard, avoided a half‑yard overage, and saved $120 on delivery.
