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.

Quarter (UK) (qr (UK))

The UK quarter, equal to 28 pounds, corresponds to 1/4 of a UK hundredweight. Historically used in grain trade, wool markets, and taxation, it reflects the older English approach to structuring weights around the stone. Its direct link to the long hundredweight made it easy for merchants to calculate loads and price goods. While obsolete today, the UK quarter remains important for historians reconstructing traditional British commerce and agricultural economies.
