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.
Femtogram (fg)
A femtogram is 10⁻¹⁵ grams, an extraordinarily small unit used primarily in molecular biology, analytical chemistry, and particle science. At this scale, masses correspond to small clusters of molecules, fragments of genetic material, or trace contaminants in environmental samples. In genomics, for example, the femtogram level may represent the mass of DNA extracted from just a few cells, pushing the limits of current sequencing technologies. Advanced mass spectrometers and nanoscale resonators can detect femtogram-level differences, revealing chemical changes invisible at larger scales. The femtogram symbolizes the reach of modern science into realms once thought beyond measurement. As techniques continue to improve, femtogram-level precision will become increasingly common in nanotechnology and biophysics.
