# 00000 Gauge U.S. Standard Gauge — Sheet Metal Thickness in Inches and Millimetres

00000 gauge us standard is 0.4375 in (11.113 mm) thick. That figure is on the USG — gauge is a material-specific numbering scheme, not a unit, so the same number is a different thickness in another material.

- **Gauge**: 00000

- **Gauge system**: USG
- **Thickness**: 0.4375 in (11.113 mm)
- **Weight**: 17.500 lb/ft² (85.44 kg/m²)

## Sources and Method for 00000 Gauge U.S. Standard Gauge

### U.S. Standard Gauge gauge thicknesses

- **Source**: 15 U.S.C. 206 (Act of Mar. 3, 1893, ch. 221, 27 Stat. 746) — U.S. Standard Gauge for sheet and plate iron and steel; 15 U.S.C. 206 statutory weights; MSG (41.82 lb/ft2 per inch), galvanized zinc allowance, and Brown & Sharpe formula per docs/research/data-sourcing.md §3.7
- **Method**: computed
- **Verified against**: Wikipedia Sheet metal, Standard sheet metal gauges table (CC BY-SA 4.0) — 137/137 checks passed at 0.05 mil

### Assumptions

- Gauge is a numbering scheme, not a unit. A thickness is only meaningful with its material and gauge system stated.
- Sheet is supplied to a mill tolerance around these nominal thicknesses; measure the stock when the fit matters.
- Dataset scope: EXCLUDED: stainless steel (genuinely ambiguous convention, only one source in hand), zinc, copper, brass, steel tube wall.

## Common Questions About 00000 Gauge U.S. Standard Gauge

### How thick is 00000 gauge us standard?

00000 gauge us standard is 0.4375 in (11.113 mm) thick, on the USG.

### What is 00000 gauge in mm?

00000 gauge us standard is 11.113 mm. Gauge is not a unit — the same number means a different thickness in a different material, so the material has to be stated with it.

### How much does 00000 gauge us standard weigh per square foot?

17.500 lb per square foot (85.44 kg per square metre).
