About these units
Neutron Mass (mₙ)
The neutron is slightly heavier than the proton, with a mass of 1.67492749804 × 10⁻²⁷ kilograms. This subtle difference has profound implications: it allows neutrons to undergo beta decay outside the nucleus, transforming into protons, electrons, and antineutrinos. Neutrons play a crucial role in nuclear reactions, especially in reactors and stars. Their ability to penetrate atomic nuclei (due to lack of electric charge) makes them highly effective in initiating fission or fusion processes. The neutron mass helps determine nuclear binding energy and isotopic stability, shaping the entire periodic table.
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.
