Enter the number of pile caps, the radius, and the height into the calculator to determine the pile quantity (volume).

Pile Quantity Formula

The following equation is used to calculate the Pile Quantity.

PQ = pi*r^2*h*C
  • Where PQ is the pile quantity (m^3)
  • r is the radius (m)
  • h is the height (m)
  • #C is the number of caps

To calculate the pile quantity, multiply the radius squared by pi times the height, then multiply by the number of caps.

What is a Pile Quantity?


Pile quantity is the total volume occupied by a set of concrete piles.

How to Calculate Pile Quantity?

Example Problem:

The following example outlines the steps and information needed to calculate Pile Quantity.

First, determine the radius. In this example, the radius is measured to be 2m.

Next, determine the height. The height of each pile is found to be 3m.

Next, determine the number of pile caps. The number of pile caps for this example is 3.

Finally, calculate the pile quantity using the formula above:

PQ = pi*r^2*h*#C

PQ = 3.14159*2^2*3*3

PQ = 113.097 m^3
