About these units
Milligram (mg)
A milligram is one-thousandth of a gram and essential for measuring extremely small masses with precision. Pharmacology relies heavily on milligrams to dose medications safely and consistently—especially potent drugs where differences of a few milligrams can be critical. In chemistry and laboratory science, milligrams are used to weigh reagents, catalysts, micro-samples, and test materials. Environmental science uses milligrams per liter or milligrams per kilogram to describe concentrations of contaminants. Its small size makes the milligram ideal for fields requiring strict quantitative control, and its stability within the metric system ensures predictable conversions during calculations.
Electron Mass (mₑ)
The electron mass, approximately 9.10938356 × 10⁻³¹ kilograms, is a fundamental constant of nature and a cornerstone of atomic physics. Because electrons determine atomic structure, bonding, and electrical properties, their mass plays a crucial role in chemistry and solid-state physics. The smallness of the electron mass allows quantum phenomena to dominate electron behavior, enabling orbitals, tunneling, and band structures in materials. Electrons' tiny mass also affects how atoms interact with electromagnetic radiation, influencing spectral lines and optical properties. In particle physics, the electron mass is one of the defining parameters of the Standard Model, impacting interactions across quantum electrodynamics (QED) and beyond.
