About these units
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.
Centigram (cg)
A centigram, equal to 1/100 of a gram, is an intermediate unit not frequently encountered in everyday life but occasionally useful in laboratory settings and chemical formulations. Its size offers a compromise between the larger gram and the smaller milligram, especially in contexts like dietetics, powdered chemicals, or small-scale industrial ingredients. Though not widely used, the centigram's value lies in its flexibility—providing a metric option for moderate precision without resorting to decimals.
