About these units
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.
Kiloton (Metric) (kt)
A kiloton, equal to 1,000 metric tons, is used in large-scale industrial, geological, and agricultural contexts. However, the term is better known for expressing explosive yields, particularly of nuclear weapons. Scientists estimate the energy release of explosions by comparing them to the detonation of 1,000 tons of TNT. For example, the Hiroshima bomb had a yield of about 15 kilotons. Outside military contexts, kilotons appear in discussions of carbon emissions, waste production, and global resource extraction. They provide a manageable scale for describing quantities too large for tons but not yet at the megaton level.
