How Sonotube Capacity Chart Generator Works?
To generate a capacity chart, the Sonotube Capacity Chart Generator computes the volume of every diameter and height pair you choose and lays them in a table. The process takes 4 steps.
Pick diameters
Choose the rows, such as 6 in to 24 in.
Pick heights
Choose the columns and the step, such as every 12 in.
Pick the output unit
Select cubic feet (ft³), cubic yards (yd³), cubic meters (m³) or liters (L).
Generate
The tool fills each cell with the volume and lets you copy or print the chart.
Sonotube Capacity Chart Generator Formula
The Sonotube Capacity Chart Generator evaluates the cylinder formula once per cell.
Cell volume
V(D, H) = π × (D ÷ 24)² × (H ÷ 12)ft³ for inch inputs.
Row rate
k(D) = π × (D ÷ 24)²Every cell in a row is k × H ÷ 12.
Unit switch
yd³ = ft³ ÷ 27; m³ = ft³ × 0.0283; L = ft³ × 28.32Applied to every cell.
Worked example: the 14 in × 60 in cell
- k(14) = 3.1416 × (14 ÷ 24)² = 1.0690 ft³ per ft
- V = 1.0690 × 5 = 5.345 ft³
- In other units: 0.198 yd³, 0.151 m³, 151 L

What is Sonotube Capacity Chart Generator?
A Sonotube Capacity Chart Generator is a chart tool that produces a grid of concrete capacities for a range of tube diameters and heights.
A capacity chart answers volume questions at a glance. Engineers paste charts into specifications, suppliers print them for counters and crews look up a pier without a calculator. The generator builds the grid for the units and steps you set, from a 6-column ft³ chart to a metric chart in liters.
Capacity charts show volume, not bags. Volume charts stay valid for any concrete product, while bag charts change with yield.
What are the uses of Sonotube Capacity Chart Generator?
There are 4 main uses of the Sonotube Capacity Chart Generator.
Specification sheets
Engineers include a capacity chart in project specs.
Supplier counters
Lumberyards print charts for customers.
Metric charts
Users generate the same grid in m³ or liters.
Quick takeoffs
Estimators read volumes off a chart.
