PVC Weight Formulas
Weight = cross-sectional area × length × density. The cross-section varies by shape:
| Shape | Cross-Section Area |
|---|---|
| Flat Sheet / Square Bar | W × T |
| Round Bar | π × (D/2)² |
| Square Hollow Tube | W² − (W − 2T)² |
| Round Hollow Tube | π × (R² − r²) |
| Square Angle (equal-leg) | 2 × W × T − T² |
| T Bar | W × Tf + (H − Tf) × Tw |
| C Channel | 2 × W × T1 + (H − 2T1) × T2 |
Variables: L = length, W = width, H = height, D = outer diameter, T = thickness, R = outer radius, r = inner radius, Tf = flange thickness (T bar), Tw = web thickness (T bar), T1 = flange thickness (C channel), T2 = web thickness (C channel), d = density. The calculator converts entered dimensions to meters and uses density in kg/m³. Select each dimension’s unit separately. The calculator supports sheets, solid rods, and round pipes; other rows are reference geometries.
PVC Density by Material Type
Density varies by formulation. The illustrative presets are 1.40 g/cm³ for rigid PVC and 1.52 g/cm³ for CPVC, values listed in GF Piping Systems’ vinyl technical manual. Use supplier data for the actual grade. The withdrawn ISO 4439:1979 specified 1.35–1.46 g/cm³ for unfilled, noncellular PVC-U pipes and fittings.
| PVC Type | Density (g/cm³) | Density (lbs/in³) | Max Temp | Typical Use |
|---|---|---|---|---|
| Rigid PVC / uPVC | 1.35–1.46 | 0.0488–0.0527 | 140°F (60°C) | Pipe, fittings, profiles |
| Flexible PVC (plasticized) | 1.10–1.35 | 0.0397–0.0488 | ~140°F | Cable insulation, hoses, film |
| CPVC | 1.50–1.58 | 0.0542–0.0571 | 200°F (93°C) | Hot water pipe, industrial |
| Filled PVC (CaCO₃ added) | 1.50–1.55 | 0.0542–0.0560 | 140°F | Low-cost siding, profiles |
| PVC Foam / Cellular | 0.45–0.80 | 0.0163–0.0289 | ~130°F | Sign boards, trim, cabinetry |
PVC-O wall dimensions and mass depend on the product standard, size, and pressure class. Compare manufacturer data for equivalent service.
Schedule 40 and Schedule 80 PVC Pipe Reference Weights
These illustrative uniform-wall weights use the listed outside diameters and wall thicknesses with a custom density of 0.054 lb/in³ (approximately 1.495 g/cm³). This differs from the calculator’s default rigid-PVC density of 1.40 g/cm³. Actual product weights and Schedule 80 increases depend on dimensions and compound.

Listed walls are minimum schedule values, not exact measured walls. Actual mass depends on product-specific tolerances and compound. Select Pipe / tube, then enter measured outer and inner diameters with the supplier density for a specific piece.
