About these units
Tetradrachma (Biblical Greek) (tetradrachma)
A tetradrachma weighed about 17 grams, equivalent to four drachmas. It became one of the most widely circulated silver coins in the ancient world, especially under the Athenian empire. Athenian tetradrachms, often stamped with the iconic owl design, were standardized, highly trusted, and circulated across the Mediterranean as an international currency. Although now primarily of numismatic interest, tetradrachms are key archaeological artifacts, illuminating trade networks, political authority, and artistic expression.
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.
