Calculate Concrete Cubic Yards

Concrete Volume Formula:

\[ V = \frac{L \times W \times D}{27} \]

Concrete Volume (cu yd):

Definition: This calculator estimates the volume of concrete needed in cubic yards based on length, width, and depth measurements.

Purpose: It helps construction professionals and DIYers determine how much concrete is required for slabs, footings, and other projects.

The calculator uses the formula:

\[ V = \frac{L \times W \times D}{27} \]

Where:

Explanation: The length, width, and depth are multiplied to get cubic feet, then divided by 27 to convert to cubic yards.

Details: Accurate concrete volume estimation prevents material shortages or excess, ensures structural integrity, and helps with cost planning.

Tips: Enter the length, width, and depth in feet. All values must be > 0. For irregular shapes, break into rectangular sections.

Q1: Why divide by 27?
A: There are 27 cubic feet in 1 cubic yard (3 feet × 3 feet × 3 feet).

Q2: How do I measure depth for slabs?
A: Measure the thickness in inches, then convert to feet (divide by 12).

Q3: What if my area isn't rectangular?
A: Divide irregular shapes into rectangles, calculate each separately, then sum the volumes.

Q4: Should I order extra concrete?
A: Yes, it's recommended to order 5-10% more than calculated to account for spillage and uneven subgrades.

Q5: How do I convert cubic yards to tons?
A: Multiply by 1.35 (average weight of concrete per cubic yard).
