How to use it
- Enter the length in feet.
- Enter the width in feet.
- Enter the depth in inches.
- Read the cubic feet, cubic yards, and ton estimate.
This free calculator turns the length, width, and depth of your soil project into three useful measurements: cubic feet, cubic yards, and an estimated weight in US tons. Knowing the cubic yards helps you order the right amount of fill or mulch, while the tonnage estimate lets you compare delivery costs from suppliers that charge by weight. The tool first converts the depth from inches to feet, multiplies length × width × depth to get cubic feet, then divides by 27 to get cubic yards. Finally it multiplies cubic yards by 1.3 tons per yard for a quick weight estimate. Read the results left‑to‑right: volume in cubic feet, volume in cubic yards, then weight in tons. You can round the numbers up to accommodate settling, or down if you plan to compact the soil after delivery. The calculator works instantly on any device, so you can get the numbers while standing on the site.
Pro tips
- Add 5‑10% extra volume to cover settling or compaction.
- Round up to the nearest half‑yard for easier ordering.
- Check supplier weight rates; some charge per ton, others per yard.
- Double‑check depth conversion from inches to feet before entering data.
Real-life examples
- Planning a new garden bed and need to know how much topsoil to buy.
- Estimating fill material for a driveway repair project.
- Calculating mulch volume for a landscaping makeover.
Case study
Mike needed to fill a 12 ft × 15 ft garden bed 8 in deep. Using the calculator he saw he required 5.3 cubic yards (≈7 tons). He ordered 6 cubic yards, avoiding a short‑fall and saving a delivery fee.
