About these units
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.
Microgram (µg)
A microgram is one-millionth of a gram, essential in pharmacology, nutrition science, and chemical analysis. Many vitamins, especially fat-soluble ones like vitamin D and K, are prescribed or measured in micrograms, as exceeding recommended doses can be harmful. In environmental monitoring, pollutant levels—such as airborne particulate matter—are often expressed in micrograms per cubic meter. Researchers working with catalysts or rare biological compounds rely on microgram-scale measurements for precise experiments. The microgram is indispensable in fields requiring tight control over small masses that impact biological or chemical systems significantly.
