Danh từ
Số nhiều: attograms
This term is used exclusively within highly specialized scientific contexts, such as molecular biology, biochemistry, and nanotechnology. It describes masses so minute that they are typically only relevant when discussing individual large molecules or small clusters of atoms.
As a standard metric unit, it follows the pattern of SI prefixes where "atto-" denotes a factor of 10^-18. It is rarely encountered in general academic writing and is almost entirely restricted to technical research papers and laboratory data.
