Units explained
Gigagram
A gigagram (Gg) equals 10^6 kilograms, the same as 1,000 metric tons.

From 'tun', a large medieval cask; 'metric' distinguishes it from imperial tons.
The global standard for trade, freight, and heavy industry.
Recognized internationally with the spread of the metric system in the late 19th century.
