15 U.S.C. § 206 — Standard gauge for sheet and plate iron and steel

This law sets one official gauge table for measuring the thickness and weight of sheet and plate iron and steel in the United States. The government uses this table to calculate import duties and taxes. It doesn't raise duties on anything that gets imported.
This section creates a single official "standard gauge" — a numbered scale for describing how thick a sheet or plate of iron or steel is, and how much it weighs.
The gauge runs from number 0000000 (the thickest) down to number 38 (the thinnest). For each gauge number, the table gives: the approximate thickness as a fraction of an inch, the same thickness as a decimal, the thickness in millimeters, the weight per square foot in ounces and in pounds, the weight per square foot in kilograms, and the weight per square meter in both kilograms and pounds. For example, gauge 0000000 is about half an inch (12.7 millimeters) thick and weighs about 20 pounds per square foot, while gauge 38 is about six-thousandths of an inch (0.16 millimeters) thick and weighs about a quarter pound per square foot.
This is the only gauge the United States may use to figure out the duties and taxes owed on sheet and plate iron and steel. But using this gauge for that purpose does not raise the duty owed on anything that gets imported.
For the purpose of securing uniformity the following is established as the only standard gauge for sheet and plate iron and steel in the United States of America, namely:
Number of gauge | Approximate thickness in fractions of an inch | Approximate thickness in decimal parts of an inch | Approximate thickness in millimeters | Weight per square foot in ounces avoirdupois | Weight per square foot in pounds avoirdupois | Weight per square foot in kilograms | Weight per square meter in kilograms | Weight per square meter in pounds avoirdupois |
