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.
Atomic Mass Unit
One unified atomic mass unit (u) is defined as 1/12 the mass of a carbon-12 atom, about 1.6605E-27 kg.
Introduced to give atomic and molecular masses convenient numerical values.
Atomic, molecular, and nuclear physics and chemistry.
The unified (carbon-12) scale was adopted by IUPAC and IUPAP in 1960-1961.
