How to use it

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

What it does – The Dirt Volume Calculator takes the length, width, and depth of a planned fill area and instantly returns three key measurements: cubic yards, cubic feet, and an approximate tonnage. Knowing the cubic yards tells you how many dump‑truck loads to order, while cubic feet is useful for smaller equipment or for comparing to product specifications. The ton estimate uses the industry standard of 1.3 US tons per cubic yard, giving you a quick sense of material weight for delivery limits and cost. Simply type your dimensions, hit calculate, and the tool does the conversions for you. No manual math, no guesswork – just clear numbers you can trust when you place an order or plan a project. You can also round the results to the nearest whole number for easier ordering, or keep the decimals for precise budgeting.

Pro tips

  • Add a 10% waste allowance to cover settling and spillage.
  • Round up cubic yards to the nearest 0.5 when ordering truckloads.
  • Check local delivery weight limits before finalizing the ton estimate.
  • Convert depth from inches to feet (divide by 12) before entering values.

Case study

Mike needed 3‑yard mulch for his backyard. He entered 12 ft × 8 ft × 6 in, got 2.22 yd³ and 2.9 tons, rounded up to 3 yd³, ordered that amount and avoided a costly second delivery.

Frequently asked questions

How do I input depth measured in inches?
Enter the depth value in inches; the calculator converts it to feet automatically.
What conversion does the tool use for weight?
It multiplies cubic yards by 1.3 US tons per cubic yard to give an approximate tonnage.
Why is cubic yard more useful than cubic foot?
Cubic yards match standard dump‑truck capacities and most bulk‑material pricing.
Do I need to round the results?
Round up to the next whole or half yard for ordering; keep decimals for budgeting if needed.
Can I use the calculator for sand or gravel?
Yes, the volume calculations are the same; adjust the weight factor if your material differs from the 1.3 tons per cubic yard estimate.
