About these units
Megagram (Mg)
A megagram, equal to 1,000 kilograms, is identical in quantity to the metric ton (tonne). While "tonne" is common in daily life, Mg is preferred in engineering, environmental science, and formal scientific writing because it is unambiguous and adheres strictly to SI conventions. Megagrams are used to express masses of vehicles, construction materials, waste output, or agricultural yields in large-scale analyses. The unit is especially useful in Earth sciences, where megagram quantities describe biomass, sediment transport, or volcanic emissions.
Exagram (Eg)
An exagram, equal to 10¹⁵ kilograms, is used to describe masses of planets, moons, and extremely large terrestrial reservoirs (e.g., total mass of Earth's atmosphere ≈ 5 Eg). Because of its enormous scale, the exagram rarely appears outside astrophysics or large-scale geophysics. When used, however, it provides a powerful sense of magnitude—allowing scientists to describe Earth systems at the grandest scales with simple, comprehensible numbers.
