How to use it

  1. Enter length in feet.
  2. Enter width in feet.
  3. Enter depth in inches.
  4. Click Calculate to see cubic yards, tons, and cubic feet.

What it does – You input the length and width of the area in feet and the depth of fill in inches. The tool converts those dimensions to cubic yards, then multiplies by 1.3 to give an approximate weight in US tons, and also shows the raw cubic‑feet volume.

Why it matters – Knowing cubic yards helps you order the right amount of dirt, avoiding costly over‑orders or shortfalls. The ton estimate lets you compare material costs that are often priced per ton. Cubic‑feet is useful for small‑scale calculations or when contractors quote in that unit.

How to read the results – The first number is the volume you’ll need in cubic yards (the standard bulk‑material unit). The second tells you roughly how many tons to expect. The third is the same volume expressed in cubic feet for quick cross‑checks.

Pro tips

  • Add 10% extra volume for compaction and settling.
  • Round up to the nearest 0.1 cubic yard to avoid under‑ordering.
  • Verify the depth measurement in inches before converting.
  • Compare supplier quotes in both tons and cubic yards to get best price.

Real-life examples

  • A homeowner planning a new garden bed needs to know how much topsoil to order.
  • A contractor preparing a driveway base wants to calculate the dirt volume and weight for truck loads.
  • A landscaper estimating fill for a backyard pond requires both cubic yards and tons to price the job.

Case study

Sam needed 2 × 4 ft garden beds 6 in deep. Using the calculator, he saw the project required 0.44 cubic yards, about 0.57 tons. He ordered 0.5 yd³ and saved $45 by avoiding an extra truck load.

Frequently asked questions

How do I convert depth from inches to feet?
The calculator does the conversion automatically; just enter the depth in inches.
Why is the ton estimate only approximate?
Dirt density varies, so the tool uses a standard 1.3 tons per cubic yard as a common average.
Can I use the results for ordering multiple truck loads?
Yes, multiply the cubic‑yard total by the number of loads or by the truck’s capacity.
What if my site isn’t a perfect rectangle?
Break the area into smaller rectangles, calculate each, then add the results.
Is the calculator suitable for sand or gravel?
It’s calibrated for typical garden dirt; for sand or gravel use the supplier’s specific weight factor.
