Conversion Tables and Units of Quantity

Conversion Tables

In January of 1989, The United States adopted the Harmonized Commodity Description and Coding System (Harmonized System, "HS") as the nomenclature for classifying both exports and imports. The Harmonized System collects information based on the metric standard. The following tables will assist data users in converting to metric quantities and values.
