Why this site

Ingredient-specific conversions, cited standards and printable tables, checked for consistency. Each value is traced to a source you can check (NIST, ASTM, the National Electrical Code, the USDA, the Craft Yarn Council), and the converter and the printed table are generated from the same data so they always agree. How we check our numbers.
