How Sonotubes per Cubic Meter Calculator Works?
To count tubes per cubic meter, the Sonotubes per Cubic Meter Calculator divides 1 cubic meter (m³) by the volume of one metric form. The process takes 4 steps.
Enter the form size
Type the diameter in centimeters (cm) and depth in meters (m).
Calculate the form volume
The calculator finds the fill of 1 form in m³ and liters (L).
Divide 1 m³ by the form
The tool returns forms per m³.
Scale to the delivery
Enter the delivered m³ to count forms filled.
Sonotubes per Cubic Meter Calculator Formula
The Sonotubes per Cubic Meter Calculator uses metric volumes only.
Forms per m³
T = 1 ÷ V_form (m³)Or 1,000 ÷ V_form (L).
Forms from a load
N = ⌊Q ÷ V_form⌋Q is the delivered m³.
Meters of form per m³
L = 1 ÷ (π × (D ÷ 200)²)D in cm.
Worked example: 30 cm × 1.2 m forms, 2 m³ delivered
- V_form = 0.0848 m³ (84.8 L)
- T = 1 ÷ 0.0848 = 11.79 forms per m³
- 2 m³ fills ⌊23.58⌋ = 23 forms
Sonotubes per Cubic Meter Calculator Conversion Table
The forms per cubic meter conversion table lists how many metric forms 1 m³ (1.31 yd³) fills at 0.9 m, 1.2 m and 1.5 m depths.
| Diameter | Forms at 0.9 m | Forms at 1.2 m | Forms at 1.5 m | Meters of form per m³ |
|---|---|---|---|---|
| 15 cm | 62.9 | 47.2 | 37.7 | 56.6 m |
| 20 cm | 35.4 | 26.5 | 21.2 | 31.8 m |
| 25 cm | 22.6 | 17.0 | 13.6 | 20.4 m |
| 30 cm | 15.7 | 11.8 | 9.4 | 14.1 m |
| 35 cm | 11.5 | 8.7 | 6.9 | 10.4 m |
| 40 cm | 8.8 | 6.6 | 5.3 | 8.0 m |
| 45 cm | 7.0 | 5.2 | 4.2 | 6.3 m |
| 60 cm | 3.9 | 2.9 | 2.4 | 3.5 m |
Values are net. Reduce by about 10% for waste.
What is Sonotubes per Cubic Meter Calculator?
A Sonotubes per Cubic Meter Calculator is a metric ratio tool that shows how many round forms one cubic meter of concrete fills.
Plants in metric countries sell concrete by the m³. One m³ fills 14.1 m of 30 cm form, or 11 piers at 1.2 m deep. The calculator turns an order or a leftover load into a form count.
The tool suits builders planning around a minimum load, often 1 m³ to 3 m³, who want to know how many piers that load covers.
What are the uses of Sonotubes per Cubic Meter Calculator?
There are 4 main uses of the Sonotubes per Cubic Meter Calculator.
Metric ordering
Builders match form counts to m³ orders.
Minimum loads
Crews plan extra forms to use a minimum load.
Pump planning
Site leads compare form counts with the pump minimum.
Mixer trucks
Operators split a load across planned forms.
