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.
Earth's Mass (M⊕)
Earth's mass is approximately 5.972 × 10²⁴ kilograms, a fundamental parameter in planetary science and orbital mechanics. It governs Earth's gravitational interaction with the Moon, Sun, and artificial satellites and shapes geological processes such as plate tectonics and atmospheric retention. Planetary scientists use Earth masses to compare exoplanets, enabling quick insights into habitability, composition, and gravitational characteristics.
