Units explained
Quintal (metric)
The metric quintal (q) equals 100 kilograms.
From Latin 'centenarius' (hundredweight) via Arabic 'qintar'.
Agriculture across India, Europe, and Latin America for grain and produce.
Fixed at 100 kg with the spread of the metric system in the 19th century.
Gigagram
A gigagram (Gg) equals 10^6 kilograms, the same as 1,000 metric tons.
From the SI prefix 'giga-' (from Greek 'gigas', giant).
Bulk commodity, emissions, and freight accounting.
The giga- prefix entered the SI in 1960.
