Cubic Yard Calculator
Convert rectangular dimensions into cubic yards.
Calculation example
Inputs: Length: 27 ft, Width: 1 ft, Depth: 1 ft
Result: 1 cubic yard
A 27 by 1 by 1 foot volume equals 1 cubic yard.
Formula
Cubic yards = length × width × depth ÷ 27 when dimensions are in feet.
How to use this calculator
Multiply length, width and depth, then divide cubic feet by 27 when the inputs are in feet.
Before you calculate
Measure the project dimensions as accurately as practical and keep all measurements in compatible units. For material products, use the coverage, yield, density, or package size stated by the manufacturer or supplier rather than a generic assumption.
Choose the waste allowance based on the project shape, installation method, cutting requirements, and material characteristics. A simple rectangular estimate may need adjustment for openings, corners, slopes, joints, patterns, compaction, or other site conditions.
Understanding the result
The calculator provides a planning estimate based on the inputs shown above. It is not a substitute for project drawings, structural design, manufacturer instructions, or local requirements. Before ordering, compare the calculated quantity with the supplier's package sizes and ordering units.
Tips
- Use feet for all three inputs when using this conversion.
- For ordering, confirm supplier conventions and compaction.
