About these units
Decigram (dg)
A decigram equals 1/10 of a gram and appears in older scientific literature, pharmaceutical compounding, and some food chemistry applications. Today, milligrams and grams are more common, but decigrams still offer practical value when describing masses that naturally fall between these scales, such as certain supplements or cosmetic ingredients. The decigram remains a reminder of the metric system's logical progression, offering users a consistent, scalable set of 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.
