About these units
Picogram (pg)
A picogram, or 10⁻¹² grams, is widely used in molecular biology, biochemistry, and medicine. Hormones, signaling molecules, and certain viruses fall within the picogram mass range. Laboratories often quantify DNA or RNA using picograms, especially in single-cell analysis. Cellular processes frequently involve minuscule quantities of molecules, so picogram measurements allow researchers to study gene expression, protein synthesis, and chemical reactions with extreme accuracy. Diagnostic tests—such as those for biomarkers in blood—often require detection at picogram per milliliter concentrations. The picogram is a crucial bridge between the molecular scale and measurable laboratory practice, enabling breakthroughs in medical diagnostics and biotechnology.
Exagram (Eg)
An exagram, equal to 10¹⁵ kilograms, is used to describe masses of planets, moons, and extremely large terrestrial reservoirs (e.g., total mass of Earth's atmosphere ≈ 5 Eg). Because of its enormous scale, the exagram rarely appears outside astrophysics or large-scale geophysics. When used, however, it provides a powerful sense of magnitude—allowing scientists to describe Earth systems at the grandest scales with simple, comprehensible numbers.
