How to use it
- Enter the length in feet.
- Enter the width in feet.
- Enter the depth in inches.
- Read the cubic yards, tons and cubic feet results instantly.
The calculator turns the dimensions of your project into three useful quantities: cubic yards of gravel, the approximate weight in tons, and the total cubic feet. Knowing the cubic yards lets you order the right amount of material, avoiding costly over‑orders or shortfalls. The ton estimate helps you compare prices that are quoted by weight, while the cubic‑foot figure is handy for checking against local fill limits. Simply enter length and width in feet and depth in inches; the tool instantly converts depth to feet, multiplies to get volume in cubic feet, then divides by 27 for cubic yards and multiplies by 1.4 to get tons. The results are rounded to two decimals for easy reading. You can use the numbers to plan a waste allowance or to verify delivery quotes.
Pro tips
- Add 5‑10% extra for compaction and spillage.
- Round up to the nearest whole cubic yard when ordering.
- Check supplier weight rates; 1 cubic yard ≈ 1.4 tons.
- Measure depth accurately; a 1‑inch error changes volume noticeably.
Real-life examples
- Building a new driveway and need exact gravel quantity.
- Filling a garden bed to a specific depth for landscaping.
- Estimating material for a backyard pathway project.
Case study
Sarah needed a 12‑ft by 8‑ft patio with a 4‑in depth of gravel. The calculator showed 1.19 cubic yards (≈1.7 tons). She ordered 2 cubic yards, avoiding a shortfall and saving $45 on the extra material.
