Cubic Yards Calculator
Enter length, width, and depth to get the volume in cubic yards and cubic feet — for concrete, soil, mulch, gravel, or sand.
Dimensions
Works for concrete, soil, mulch, gravel, sand — anything sold by the cubic yard.
Volume
Cubic yards
0 yd³
0 cubic feet
Cubic yards = length × width × depth (all in feet) ÷ 27. Add 5–10% waste for most bulk materials.
How to calculate cubic yards
Convert all measurements to feet, multiply length × width × depth for cubic feet, and divide by 27 for cubic yards. It's the universal volume formula for bulk materials.
Measure dig and fill areas from a scan
ProBuildCalc turns your iPhone's LiDAR scanner into a job-site measuring kit — walk the space and it captures the square footage, material takeoff, and a blueprint automatically. No tape measure, no graph paper.
Cubic yards FAQ
- How do I calculate cubic yards?
- Multiply length × width × depth, all in feet, then divide by 27 (since a cubic yard is 27 cubic feet). If your depth is in inches, divide it by 12 first to convert to feet.
- How many cubic feet are in a cubic yard?
- There are 27 cubic feet in one cubic yard (3 ft × 3 ft × 3 ft).
- How do I convert inches of depth to cubic yards?
- Divide the depth in inches by 12 to get feet, multiply by the length and width in feet, then divide by 27. This calculator does the conversion when you pick inches.
- What materials are sold by the cubic yard?
- Concrete, topsoil, mulch, compost, gravel, sand, and fill dirt are all commonly ordered by the cubic yard. Add 5–10% for waste and compaction.
