About these units
Gigagram (Gg)
A gigagram equals 1,000 megagrams, or one million kilograms. It is used in industrial-scale output, national food production statistics, and environmental assessments, such as annual emissions of pollutants. Governments and researchers analyzing natural resource consumption, waste management, or ecological footprints frequently rely on gigagram-level reporting. The Gg sits at the intersection of human-scale systems and planetary-scale studies, offering clarity for large quantities.
Petagram (Pg)
A petagram, equal to 10¹² kilograms, is used almost exclusively in global environmental science and earth system modeling. Planetary-scale carbon budgets—for example, the total carbon stored in Earth's soils or forests—are expressed in petagrams. The Amazon rainforest alone holds on the order of 100 Pg of carbon. Using petagrams helps researchers track changes in Earth's climate balance and evaluate feedback loops in the carbon cycle.
