About these units
Gerah (Biblical Hebrew) (gerah)
A gerah, approximately 0.57 grams, is the smallest unit in the Hebrew weight system. 1 shekel = 20 gerahs Gerahs were used for minute quantities of precious metals or spices for ritual purposes. Biblical texts refer to gerahs in the context of sanctuary offerings and priestly duties. The gerah illustrates the fine-grained precision required for temple rituals and daily commerce in the ancient Near East.
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.
