A gigagram (Gg) is a mass unit equal to one billion grams, or one million kilograms, commonly used for expressing very large masses in engineering and environmental contexts.

Why does the ton (assay) (US) vary in definition?

The US assay ton has historically differed by region and practice, so modern reporting usually specifies explicit masses to avoid confusion.

When should I use this conversion tool?

Use it when you need to relate large masses measured in gigagrams to assay tons, especially for mining reports, precious metal assays, and historical data comparisons.
