About these units
Planck Mass (mₕ)
The Planck mass, approximately 2.176434 × 10⁻⁸ kilograms, occupies a unique position in theoretical physics. Unlike particle masses, it is derived entirely from fundamental constants—Planck's constant, Newton's gravitational constant, and the speed of light. The Planck mass represents a mass scale where quantum mechanical and gravitational effects become comparable. Although enormous relative to subatomic particles (roughly the mass of a dust grain), it is considered "natural" in that it emerges from pure physics rather than empirical observation. In theoretical studies of black holes, quantum gravity, string theory, and early-universe cosmology, the Planck mass marks a boundary beyond which existing models require unification. It is a conceptual rather than practical unit, yet it provides a profound insight into the structure of physical law.
Teragram (Tg)
A teragram equals 1,000 gigagrams, or 10⁹ kilograms. It is widely used in climatology, atmospheric science, and ecology to describe the mass of carbon, nitrogen, methane, or other substances exchanged annually between Earth's systems. For example, global carbon fluxes—movement of carbon between oceans, atmosphere, and biosphere—are typically measured in teragrams. Volcanoes, wildfires, and anthropogenic emissions often release substances on this scale. Tg-level measurements give researchers insight into the stability, sustainability, and long-term trends of Earth's ecosystems.
