Disclaimer
Disclaimer for sheetgauge.com/. Our sheet metal weight calculators are reference tools — not certified engineering values. Always verify with mill certificates for critical applications.
General Disclaimer
All calculators, charts, and guides on sheetgauge.com/ are for reference and estimation purposes only. Results are not certified engineering values.
sheetgauge.com/ provides sheet metal reference tools for general use by fabricators, engineers, buyers, and students. All outputs are estimates based on standard published values.
Weight Calculator Accuracy
| Calculator Type | Typical Accuracy | When to Verify |
|---|---|---|
| Sheet / Plate weight | ±1–2% of actual | High-value procurement orders |
| Structural sections (I-beam, RHS) | ±1–3% | Before placing supply orders |
| Pipe / hollow section | ±2–4% | Always check mill certificate |
| Cost estimator | ±5–10% | Use for budgeting only — get formal quotation |
Actual weights depend on mill tolerances (ASTM A480, EN 10051, IS 1730), exact alloy composition, surface coating thickness, and measurement method. Our calculators use nominal density values and theoretical dimensions.
Gauge Standard Disclaimer
Multiple gauge systems exist (BWG, SWG, US Standard, B&S / AWG, Manufacturers’ Standard) and they assign different thicknesses to the same gauge number for different metals. Our converters apply the correct standard for each metal as per published references, but:
- Always confirm the gauge standard your supplier is using before ordering
- Gauge systems are not standardized globally — the same gauge number means different thicknesses in different countries
- For critical applications, always specify thickness in mm or inches, not gauge numbers
