Calculation results
Formula & assumptions
Material volume = π(R²−r²)l.
Values use the specified units. Calculations use floating-point arithmetic. Check input measurements and formula assumptions before applying the result.
Compare your scenarios
Save up to five results to compare changes side by side. Scenarios stay in this tab until you clear or reload it.
Using Hollow Cylinder Calculator
Measure tube material volume and internal capacity.
- Enter outer radius, inner radius, length using the units printed under each field.
- Choose Calculate, or enable live updates. Review the result labels and formula assumptions.
- Save scenarios to compare up to five variations, then copy the report or download JSON or CSV.
Example
Outer radius: 5 cm Inner radius: 4 cm Length: 30 cm Material volume · cm³: 848.23002 Internal capacity · liters: 1.5079645 Wall thickness · cm: 1
Questions & answers
What does Hollow Cylinder Calculator calculate?
Measure tube material volume and internal capacity.
Which units should I enter?
Outer radius uses cm. Inner radius uses cm. Length uses cm. Convert values to these units before calculating.
Which formula does it use?
Material volume = π(R²−r²)l.
What does the included example show?
Outer radius: 5 cm; Inner radius: 4 cm; Length: 30 cm. Result: Material volume · cm³ = 848.23002; Internal capacity · liters = 1.5079645; Wall thickness · cm = 1.
Can I compare different settings?
Yes. Save a scenario, change the inputs and save another result. Up to five scenarios are compared in this tab; they disappear when you reload or leave.
Can I export the calculation?
Copy the JSON report or download JSON and CSV with inputs, result labels and numeric values. Processing uses local JavaScript; no calculation request is sent to our server. Displayed values use up to 10 significant digits; exports retain JavaScript numeric precision.
