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 results.

What it does – You input the length and width of the area in feet and the desired depth in inches. The tool converts those numbers to cubic feet, then to cubic yards (1 cubic yard = 27 cubic feet). Finally it multiplies the cubic yards by 1.3 to give an approximate tonnage. Why it matters – Knowing the exact volume prevents ordering too little material, which can delay a project, or too much, which wastes money. How to read the results – Cubic yards is the standard measure for ordering fill dirt, cubic feet helps you visualize the space, and tons lets you compare to supplier weight quotes. The calculator works on any device, so you can measure on‑site with a phone and get the numbers instantly. No manual conversions or spreadsheet headaches required.

Pro tips

  • Add 10% extra for compaction and wind‑blown loss.
  • Round up to the nearest whole yard for ordering convenience.
  • Compare tonnage with supplier specs to avoid over‑paying.
  • Double‑check depth entry; a common mistake is entering feet instead of inches.

Real-life examples

  • Landscaping a new garden bed and need exact fill dirt volume.
  • Preparing a driveway base before pouring asphalt.
  • Filling a low‑lying yard to prevent water pooling.

Case study

Sarah needed to raise her backyard by 4 inches for a patio. Using the calculator she learned she required 2.3 cubic yards (≈3 tons). She ordered 3 tons, avoided a second delivery, and completed the patio on schedule.
