Cubic yard calculator.
Calculate cubic yards (or cubic metres) from length, width and depth in seconds. Enter the three dimensions for any excavation, slab, pour or stockpile area, and this calculator finds the volume instantly — no rows to add, no upload needed, just type and read the result. Switch between metric and imperial units at any time; whatever you've already entered converts automatically. This is a straightforward length by width by depth calculation for a simple rectangular volume, not a substitute for a real site survey on an irregular shape. Use our Cubic Yards to Tons Calculator next if you need to convert this volume into an order weight.

volume = length × width × depth. Recomputes instantly on every change, no "Calculate" button needed.
| Assumption | Value | Source |
|---|---|---|
| Volume formula | length × width × depth | Basic geometry — the volume of a rectangular prism is length times width times depth. |
This is an early-appraisal planning estimate, not a quotation or a substitute for a surveyed takeoff. Last reviewed 31 Aug 2026.
Multiply length by width by depth, all in the same unit, then convert to cubic yards — this calculator does the conversion for you automatically.
The depth of the excavation, pour or stockpile you're measuring — check your drawings or site survey for the actual figure.
Yes — switch to metric with the toggle above and enter your dimensions in metres and millimetres.
Yes — use the metric/imperial switch above the calculator. Values you've already entered convert automatically; nothing is lost switching back and forth.
