Duct thickness is expressed in gauges and millimeters. However, the conversion between gauges and millimeters doesn’t seem to follow a set of rules. So, exactly how to convert the duct thickness from gauges to millimeters?<\/p>\n\n\n\n
Generally, the thickness of HVAC ducts is standardized into 0.5 mm, 0.6 mm, 0.8 mm, 1.0 mm and 1.2 mm. The corresponding duct gauges are 26, 24, 22, 20 and 18. The most common duct thickness is 22 gauge or 0.8 mm.<\/strong><\/p>\n\n\n\n
From the above table, 26 gauge duct thickness is 0.5 mm. 24 gauge duct thickness is 0.6 mm. 22 gauge duct thickness is 0.8 mm. 20 gauge duct thickness is 1.0 mm and 18 gauge duct thickness is 1.2 mm.<\/p>\n\n\n\n
Sometimes, the conversion of duct thickness between gauges and millimeters may not follow as per the above table. For example, 26 gauge duct thickness is also 0.6 mm. This is due to thickness tolerances.<\/p>\n\n\n\n
