How Sonotube Cubic Meters Calculator Works?
To get a Sonotube concrete quantity in cubic meters (m³), the calculator converts the diameter and height to meters and applies the cylinder formula. The process takes 4 steps.
Enter dimensions
Type the tube diameter and the pour height. Inputs in inches are converted at 2.54 cm per inch.
Convert to meters
The calculator turns centimeters (cm) into meters (m). A 30 cm tube has a 0.15 m radius.
Apply the cylinder formula
The radius squared times pi (π) times the height gives the m³ fill of one tube.
Total and round
The tool multiplies by the tube count and waste margin, then rounds to 3 decimals, the precision most batching plants accept.
Sonotube Cubic Meters Calculator Formula
The Sonotube Cubic Meters Calculator uses metric base units.
Cylinder volume
V (m³) = π × (D ÷ 200)² × (H ÷ 100)D and H are in centimeters. D ÷ 200 gives the radius in meters.
Imperial to metric
V (m³) = V (ft³) × 0.0283168One cubic foot (ft³) equals 0.0283168 m³.
Yards to meters
V (m³) = V (yd³) × 0.764555One cubic yard (yd³) equals 0.764555 m³.
Worked example: one 30 cm × 120 cm tube
- r = 30 ÷ 200 = 0.15 m and h = 120 ÷ 100 = 1.2 m
- V = 3.1416 × 0.15² × 1.2 = 0.0848 m³
- 0.0848 m³ = 84.8 L = 3.00 ft³
Sonotube Cubic Meters Calculator Conversion Table
The cubic meters conversion table lists metric Sonotube fills at 1.0 m and 1.2 m depths, with the number of tubes 1 m³ of concrete fills.
| Tube diameter | m³ per 1.0 m | m³ at 1.2 m | Liters at 1.2 m | Tubes per 1 m³ at 1.2 m |
|---|---|---|---|---|
| 15 cm (5.9 in) | 0.0177 | 0.0212 | 21 | 47.2 |
| 20 cm (7.9 in) | 0.0314 | 0.0377 | 38 | 26.5 |
| 25 cm (9.8 in) | 0.0491 | 0.0589 | 59 | 17.0 |
| 30 cm (11.8 in) | 0.0707 | 0.0848 | 85 | 11.8 |
| 40 cm (15.7 in) | 0.1257 | 0.1508 | 151 | 6.6 |
| 45 cm (17.7 in) | 0.1590 | 0.1909 | 191 | 5.2 |
| 60 cm (23.6 in) | 0.2827 | 0.3393 | 339 | 2.9 |
Metric tube sizes are nominal. A 30 cm form is close to an imperial 12 in (30.5 cm) form.
What is Sonotube Cubic Meters Calculator?
A Sonotube Cubic Meters Calculator is a metric concrete calculator that reports the fill volume of round tube forms in cubic meters, the unit ready-mix plants use in Canada, the United Kingdom (UK), Australia and most of Europe and Asia.
The calculator accepts metric or imperial sizes and outputs m³ to 3 or 4 decimals. A 25 cm × 1.2 m pier needs 0.059 m³, so 1 m³ of concrete fills about 17 of those piers.
Metric jobs order concrete in steps of 0.1 m³ to 0.5 m³. The m³ total on screen is ready to round up to that step.
What are the uses of Sonotube Cubic Meters Calculator?
There are 4 main uses of the Sonotube Cubic Meters Calculator.
Metric ready-mix orders
Builders in Canada and Europe call a plant with an m³ quantity for a pier pour.
Drawing checks
Engineers compare tube volumes with quantities on metric structural drawings.
Mixed-unit projects
Crews with imperial tubes and a metric supplier convert ft³ into m³ in one step.
Concrete pump sizing
Site leads compare the total with the minimum volume a pump operator accepts for one call-out.
