About these units
Hectogram (hg)
A hectogram equals 100 grams and is common in food markets in Italy, Greece, and parts of Latin America. Consumers often purchase cheese, cold cuts, or dry goods in hectograms because it provides a comfortable scale—neither too large nor too small. In scientific contexts, hectograms sometimes appear in hydrology, meteorology, or soil science, where medium quantities are more intuitively expressed using this unit. Though overshadowed globally by the kilogram, the hectogram survives where cultural habits align with metric logic.
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.
