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.
Hundredweight (US) (cwt (US))
The US hundredweight equals 100 pounds (45.359237 kg) and is used in agriculture, livestock markets, and commodity trading. Farmers often price hay, grain, and cattle by the hundredweight. The oil and chemical industries also use it for bulk goods. Its relation to the ton (20 cwt = 1 US ton) integrates it smoothly into the US customary system. Although it complicates international trade due to conflicting definitions with the UK version, the US hundredweight remains essential in domestic commerce.
