Units explained
Metric Ton
The metric ton (t) equals exactly 1,000 kilograms; it is also called the tonne.
From 'tun', a large medieval cask; 'metric' distinguishes it from imperial tons.
The global standard for trade, freight, and heavy industry.
Recognized internationally with the spread of the metric system in the late 19th century.
Carbon-12 Atom Mass
The mass of a single carbon-12 atom is exactly 12 u by definition, about 1.9926E-26 kg.
The reference nuclide that defines the unified atomic mass scale.
The defining standard for the atomic mass unit.
Chosen as the mass standard by IUPAC and IUPAP in 1960-1961.
