Footing Concrete Calculator
Rectangular volume = length × width × depth; round pier volume = π(d/2)²h.
Inputs and units
- Footing shape: Choose Rectangular strip, Round pier.
- Length / diameter: Enter your value in the format and unit shown.
- Width (unused for round pier): Enter your value in the format and unit shown.
- Depth: Enter your value in the format and unit shown.
- Dimension unit: Choose Metres, Centimetres, Millimetres, Feet, Inches.
- Number of identical footings: Enter your value in the format and unit shown.

Calculation method
Rectangular volume = length × width × depth; round pier volume = π(d/2)²h.
Worked example
The example values are: Footing shape = strip; Length / diameter = 4; Width (unused for round pier) = 0.5; Depth = 0.3; Dimension unit = m; Number of identical footings = 1; Extra material (%) = 10
- Concrete (m³): 0.66
- Concrete (yd³): 0.8632474087
