- What is a Nanometer? - LifewireA nanometer (nm) is a unit of length in the metric system, equal to one billionth of a meter (1 x 10-9 m). Many have likely heard of it before–it’s frequently associated with nanotechnology and the creation or study of very tiny things.
- Nanotechnology - Education | National Geographic SocietyA nanometer is an extremely small unit of length—a billionth (10-9) of a meter. Just how small is a nanometer (nm)? On the nanometer-scale, materials may exhibit unusual properties. When you change the size of a particle, it can change color, for example.
- What is a nanometer? | National Nanotechnology InitiativeA nanometer is one billionth of a meter. (A meter is 39.37 inches, or slightly longer than one yard.) The prefix “nano” means “one billionth”, or 10-9, in the international system for units of weights and measures. The abbreviation for nanometer is "nm." For visual examples of the size of the nanoscale, see The Size of Nano.
- Just How Small Is “Nano”? - National Nanotechnology InitiativeIn the International System of Units, the prefix "nano" means one-billionth, or 10-9; therefore, one nanometer is one-billionth of a meter. It’s difficult to imagine just how small that is, so here are some examples: • A sheet of paper is about 100,000 nanometers thick. • A strand of human DNA is 2.5 nanometers in diameter. • A human ...
