Stainless Steel Round Tube Weight Calculator

Summary

Enter outer diameter, wall thickness, length, and stainless steel grade to instantly calculate tube weight in kg and lb.

How it works

1. Select the stainless steel grade (304, 316, or 430) to set the correct density.
2. Enter the outer diameter of the tube in millimeters.
3. Enter the wall thickness in millimeters (must be less than half the outer diameter).
4. Enter the tube length in meters or millimeters.
5. The calculator derives the inner diameter, computes the annular cross-section area, and multiplies by length and density.
6. Weight results appear instantly in kilograms and pounds.

Use cases

• Estimate material weight for structural and architectural projects.
• Calculate shipping and freight costs for stainless tube orders.
• Verify supplier weight quotes against your own calculations.
• Plan load-bearing capacity for handrails, frames, and supports.
• Compare tube weights across grades to optimize cost and performance.
• Generate quick weight summaries for fabrication cut lists.
