Concrete Pour Volume Calculator (Footing/Slab)
This calculator helps determine how much concrete is required for a footing or slab pour based on diameter, width, and depth. It converts all measurements to cubic yards, giving accurate estimations for small or large pours in foundation or floor construction.
Calculate Concrete Volume for Slab or Footing Pours
Concrete Pour Volume Formula
$$\text{Footing Pours} = \frac{ \text{Diameter} \cdot \left( \frac{\text{Width}}{12} \right) \cdot \left( \frac{\text{Depth}}{12} \right) }{27}$$
Where:
- $$Diameter$$ — number of footing holes or units
- $$Width$$ — width in inches
- $$Depth$$ — depth in inches
- $$27$$ — converts from ft³ to yd³
This formula is commonly used in site preparation and slab work, especially when pouring multiple footings or columns of the same size. All values are converted to feet and finally to cubic yards, the standard unit when ordering concrete from suppliers.
