Nano-

Definition

The prefix 'nano-' is derived from the Greek word 'nanos' meaning 'dwarf'. In the context of physics and scientific measurements, the prefix 'nano-' is used to denote one-billionth (1/1,000,000,000) of a particular unit. This prefix is commonly used to describe extremely small quantities or dimensions at the atomic and molecular scale.
