Attogram [ag]
The attogram is a metric unit of mass equal to one-quintillionth of a gram.
Key Facts:
Used in cutting-edge scientific fields like nanotechnology, physics, and molecular science
The prefix "atto-" means 10−18 (one quintillionth)
Enables measurement of extraordinarily tiny masses, such as single molecules or atoms
The attogram is vital for quantifying masses at the smallest scales currently measurable in science.
