Units explained
Teragram
A teragram (Tg) equals 10^9 kilograms, or one million metric tons.
From the SI prefix 'tera-' (from Greek 'teras', monster).
Used in large-scale environmental and industrial mass accounting.
The tera- prefix entered the SI in 1960.
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.
Teragram to Carbon-12 Atom Mass conversion formula
