The femtogram is a metric unit of mass equal to one-quadrillionth of a gram.
Key Facts:
Used in highly sensitive scientific research, including molecular biology, physics, and nanotechnology
The prefix "femto-" means 10−15 (one quadrillionth)
Measures incredibly small masses such as molecules, atoms, and nanoparticles
The femtogram allows for the detection and measurement of ultrafine masses at the atomic and molecular scale.
