How Sonotubes per Cubic Yard Calculator Works?
To count tubes per yard, the Sonotubes per Cubic Yard Calculator divides 27 cubic feet (ft³), the volume of 1 cubic yard (yd³), by the volume of one tube. The process takes 4 steps.
Enter one tube size
Type the diameter and depth.
Calculate tube volume
The calculator finds the fill of 1 tube in ft³.
Divide 27 by the tube
The tool returns tubes per yd³ as a decimal and as whole tubes.
Scale to your load
Enter a delivered volume, such as 3 yd³, to see how many tubes the load fills.
Sonotubes per Cubic Yard Calculator Formula
The Sonotubes per Cubic Yard Calculator compares a yard with a tube.
Tubes per yard
T = 27 ÷ V_tube (ft³)1 yd³ = 27 ft³.
Whole tubes
T_whole = ⌊T⌋Complete tubes per yard.
Linear feet per yard
L = 27 ÷ (π × (D ÷ 24)²)Feet of tube 1 yd³ fills.
Worked example: 10 in × 48 in tubes
- V_tube = 2.182 ft³
- T = 27 ÷ 2.182 = 12.38 tubes per yd³
- 3 yd³ fills ⌊37.13⌋ = 37 tubes
Sonotubes per Cubic Yard Calculator Conversion Table
The tubes per cubic yard conversion table lists how many tubes of each size 1 yd³ (0.765 m³) fills at 3 depths, with the total feet of tube.
| Diameter | Tubes at 36 in | Tubes at 48 in | Tubes at 60 in | Linear feet per yd³ |
|---|---|---|---|---|
| 6 in | 45.8 | 34.4 | 27.5 | 137.5 ft |
| 8 in | 25.8 | 19.3 | 15.5 | 77.3 ft |
| 10 in | 16.5 | 12.4 | 9.9 | 49.5 ft |
| 12 in | 11.5 | 8.6 | 6.9 | 34.4 ft |
| 14 in | 8.4 | 6.3 | 5.1 | 25.3 ft |
| 16 in | 6.4 | 4.8 | 3.9 | 19.3 ft |
| 18 in | 5.1 | 3.8 | 3.1 | 15.3 ft |
| 24 in | 2.9 | 2.1 | 1.7 | 8.6 ft |
Values are net. Reduce by about 10% for waste.
What is Sonotubes per Cubic Yard Calculator?
A Sonotubes per Cubic Yard Calculator is a ratio tool that shows how many tubes of a given size one cubic yard of ready-mix concrete fills.
Ready-mix is sold by the yard, and the question on site is how far a yard goes. One yard fills 49.5 ft of 10 in tube, or about 12 piers at 48 in deep. The calculator turns a delivered load into a pier count.
The ratio helps decide whether a truck is worth ordering: when one yard covers the whole job, bagged concrete is often cheaper.
What are the uses of Sonotubes per Cubic Yard Calculator?
There are 4 main uses of the Sonotubes per Cubic Yard Calculator.
Truck vs bags
Owners see whether a job reaches a full yard.
Load planning
Crews know how many piers each yard covers.
Extra forms
Site leads set spare tubes to use a load minimum.
Quick estimates
Estimators price piers by yard fraction.
