Size effects are active for common annealed grades. Temper and grain condition drive acceptance more than the thickness figure does.

Conversions are exact at 25.4 mm per inch. Gauge numbers are shown only where the stainless sheet gauge table actually reaches; the table stops near 0.0125 in (30 gauge), which is why foil is ordered in decimals.
