In 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 strand of human DNA is 2.5 nanometers in diameter. A human hair is approximately 80,000- 100,000 nanometers wide.

The nanometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: nm), or nanometer (American spelling), is a unit of length in the International System of Units (SI), equal to one billionth (short scale) of a meter (0.000000001 m) and to 1000 picometres. One nanometre can be expressed in scientific ...

• A strand of human DNA is 2.5 nanometers in diameter. • There are 25,400,000 nanometers in one inch. • A human hair is approximately 80,000–100,000 nanometers wide. • A single gold atom is about a third of a nanometer in diameter. On a comparative scale, a sphere with a diameter of 1 nanometer is to a softball as a softball is to the ...
May 21, 2024 · To get the length of a nanometer in perspective, pretend you were shrunk in size about 1.5 billion times, so your height become 1 nanometer. A human would be about 1.5 million km tall, from our new perspective. This is about 120 Earth diameters, or three times longer than the distance from the Earth to the Moon.
Jul 30, 2021 · A nanometer (nm) is a unit of length in the metric system, equal to one billionth of a meter (1 x 10-9 m). ... Viruses range from 50 and 200 nanometers in size. The ...
How big is a nanometer? A nanometer (nm) is 1,000 times smaller than a micrometer. It is equal to 1/1,000,000,000th or one-billionth of a meter. When things are this small, you can't see them with your eyes, or a light microscope. Objects this small require a special tool called a scanning probe microscope. (link to SPM page)
