Description

Atomic Mass Unit (u): Essential for Molecular Weights

The atomic mass unit (u) is a unit of mass commonly used to express atomic and molecular weights. It is numerically equivalent to the dalton, where 1 u = 1.66053906660 × 10⁻²⁷ kg. This unit simplifies the representation of atomic-scale masses in scientific equations and analysis.

Utilized in fields such as chemistry, physics, and molecular biology, the atomic mass unit is crucial for interpreting molecular formulas, chemical reactions, and spectrometry data.

Mark: Historic European Mass Unit

The mark is a historical unit of mass used in various parts of Europe, particularly for weighing precious metals. One mark equals approximately 0.2488 kilograms. It played a significant role in medieval trade and currency systems.

Although obsolete today, the mark is relevant for historians, numismatists, and collectors examining historical weights and standards in European economic history.
