About these units

Gram (g)

The gram is one-thousandth of a kilogram and is widely used in everyday life for measuring food, medicines, small components, and scientific samples. Its scale is convenient for objects too light to measure in kilograms yet too heavy for milligrams. Chemists, biologists, and lab technicians rely heavily on grams to quantify reagents, biological specimens, powders, and liquids. The gram appears frequently in nutrition labels, recipes, and manufacturing specifications. As a metric unit, the gram benefits from simplicity and ease of conversion—just move the decimal to reach milligrams or kilograms. Its intuitive scale makes it one of the most universally recognized units in the world.

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.
