One nanometer is about as long as your fingernail grows in one second. The illustration below has three visual examples of the size and the scale of nanotechnology, showing just how small things at the nanoscale actually are.
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 ...
Nanoscientists work at incredibly small scales. To illustrate just how small a nanometer is, we blow a human hair to the size of the Empire State Building, a...
A nanometre is a billionth of a metre. Nanoscale can refer to things less than 100 nanometres in size, or to materials so small that they behave differently to normal.
A 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.
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)
• 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.
