About these units
Decigram (dg)
A decigram equals 1/10 of a gram and appears in older scientific literature, pharmaceutical compounding, and some food chemistry applications. Today, milligrams and grams are more common, but decigrams still offer practical value when describing masses that naturally fall between these scales, such as certain supplements or cosmetic ingredients. The decigram remains a reminder of the metric system's logical progression, offering users a consistent, scalable set of 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.
