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.
Drachma (Biblical Greek) (drachma)
The drachma, roughly 4.3 grams, served as the principal Greek silver unit for centuries. Both a mass and a monetary unit, the drachma appears extensively in ancient writings, from philosophy to commerce to biblical passages. The term originates from "a handful," linking the weight to early barter practices. Over time, it became a symbol of civic identity—different city-states minted distinct drachmas with unique iconography. Its influence survives in the name of Greece's former national currency, the drachma, reinforcing its cultural legacy.
