Stainless Steel Size & Weight Charts
Quick-reference charts for SS sheet gauges, sheet weights, pipe schedules, round bars and square tubes. All weights are for SS 304 (7.93 g/cm³).
SS sheet gauge to mm chart
Standard stainless steel gauge thickness with weight per square metre and per standard sheet. In the Indian market, gauges are often rounded — for example 14G ≈ 2.0 mm, 16G ≈ 1.6 mm, 18G ≈ 1.2 mm, 20G ≈ 0.9 mm — so always confirm thickness in mm when ordering.
