How to use it

  1. Enter length in feet.
  2. Enter width in feet.
  3. Enter depth in inches and click Calculate.

What it does – The calculator turns the dimensions of a dirt fill (length, width, depth) into three useful measures: cubic yards, cubic feet, and an estimated weight in tons. Knowing cubic yards lets you order the right amount of material from a supplier; cubic feet is handy for comparing with other volume‑based projects, and the ton estimate helps you budget for delivery fees that are often weight‑based. The math uses standard conversions (12 in = 1 ft, 27 ft³ = 1 yd³) and a weight factor of 1.3 US tons per cubic yard. How to read the results – Cubic yards is the primary order quantity, cubic feet shows the exact volume, and tons gives a quick weight approximation for transport planning.

Pro tips

  • Add 5‑10% extra for compaction.
  • Round up to the nearest half‑yard for ordering.
  • Check supplier’s minimum load size.
  • Double‑check depth conversion from inches to feet.

Real-life examples

  • Homeowner spreading a new lawn base.
  • Landscape contractor filling a garden bed.
  • DIYer preparing a sandbox for kids.

Case study

Sarah needed 2.2 cubic yards of soil for a garden patch. Using the calculator, she entered 10 ft × 12 ft × 6 in, saw 2.22 yd³ (≈2.9 tons) and ordered exactly that amount, avoiding a costly over‑order.

Frequently asked questions

How do I convert the calculator results to tons?
Multiply the cubic yards by 1.3 US tons per cubic yard; the tool does this automatically.
Why does the calculator show cubic feet as well?
Cubic feet provides a more precise volume for small projects and helps compare different materials.
Do I need to account for soil compaction?
Yes, add a 5‑10% waste allowance to the cubic yard result to cover settling.
What if my depth is in centimeters?
Convert centimeters to inches (1 in ≈ 2.54 cm) before entering the depth.
Is the ton estimate exact?
It’s an approximation based on 1.3 tons per cubic yard; actual weight can vary slightly with moisture content.
