About these units
Electron Mass (mₑ)
The electron mass, approximately 9.10938356 × 10⁻³¹ kilograms, is a fundamental constant of nature and a cornerstone of atomic physics. Because electrons determine atomic structure, bonding, and electrical properties, their mass plays a crucial role in chemistry and solid-state physics. The smallness of the electron mass allows quantum phenomena to dominate electron behavior, enabling orbitals, tunneling, and band structures in materials. Electrons' tiny mass also affects how atoms interact with electromagnetic radiation, influencing spectral lines and optical properties. In particle physics, the electron mass is one of the defining parameters of the Standard Model, impacting interactions across quantum electrodynamics (QED) and beyond.
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.
