How to use it

  1. Enter the length in feet.
  2. Enter the width in feet.
  3. Enter the depth in inches.
  4. Read the cubic yards, tons, and cubic feet results.

What it does – The Dirt Tons Calculator takes the length, width, and depth of the area you plan to fill and instantly gives you three useful figures: cubic yards, the approximate weight in US tons, and cubic feet. Why it matters – Knowing cubic‑yard number helps you order the right amount of material, while the ton estimate lets you compare prices that are often quoted per ton. How to read – The cubic‑yard number is the standard volume unit for bulk dirt, the ton figure is the weight (using the industry‑standard 1.3 tons per cubic yard), and cubic feet is useful for smaller‑scale calculations or for checking your input dimensions. You can also use the cubic‑foot result to verify that your depth entry was correct, especially when working with inches. The calculator updates instantly as you change any dimension, so you can experiment with different depths to see how the weight and volume shift.

Pro tips

  • Add 5‑10% extra for compaction and settling
  • Round up to the nearest whole ton when ordering to avoid shortfalls
  • Compare supplier prices per ton after converting your volume
  • Double‑check depth entry; inches are easy to mistype

Real-life examples

  • A homeowner estimating soil for a new garden bed
  • A contractor planning fill for a driveway ramp
  • A landscaper ordering mulch for a large park area

Case study

Maria needed 12 cubic yards of topsoil for her backyard garden. Using the calculator she entered 20 ft × 15 ft × 6 in and saw 13.3 cubic yards and 17 tons, so she ordered 14 cubic yards to cover compaction, avoiding a costly second delivery.

Frequently asked questions

How do I convert cubic yards to tons?
Multiply the cubic yards by 1.3 US tons per cubic yard; the calculator does this automatically.
Why is the weight shown as an approximate?
Because actual dirt density can vary, the 1.3 ton factor is an industry average.
Can I use the calculator for sand or gravel?
Yes, but adjust the weight factor; sand and gravel are denser than the default 1.3 tons per cubic yard.
Do I need to include a waste factor?
It’s recommended to add 5‑10% extra volume for compaction and spillage.
Is the result in US tons or metric tons?
The calculator uses US tons (2,000 lb) as the standard unit.
