What is nanometer used for?
A nanometer is a unit of spatial measurement that is 10-9 meter, or one billionth of a meter. It is commonly used in nanotechnology, the building of extremely small machines.
Is nanometer The smallest unit?
A nanometer is 1,000 times smaller than a micrometer. In other words, one micrometer (μm) is 1,000 nanometers….The Metric Table.
| Metric | Power | Factor |
|---|---|---|
| Micrometer (μm) | 10-6 | 0.000 001 |
| Nanometer (nm) | 10-9 | 0.000 000 001 |
| Picometer (pm) | 10-12 | 0.000 000 000 001 |
What is an example of a nanometer?
The Amazing Smallness of Our World Your fingernails grow at the rate of about 1 nanometer per second. A single water molecule is about 1.5 nanometers. A strand of human DNA is 2.5 nanometers in diameter. A single hemoglobin molecule is 5 nanometers across.
What is before nanometer?
The Metric System
| Prefix | Measurement | Scientific Notation |
|---|---|---|
| Centi- | 0.01 m | 1 x 10-2 m |
| Milli- | 0.001 m | 1 x 10-3 m |

How many atoms is a nanometer?
There are about 20 atoms along this line, so one nanometer is about the width of 2 silicon atoms, and the gate length of a 20nm NAND flash chip would be 40 atoms across.
How do you measure 1 nanometer?
A nanometer is one billionth of a meter, 0.000000001 or 10-9 meters….How Small is Nano
- a human hair is about 60,000 – 100,000 nm wide.
- a fingernail grows 1 nm per second.
- a DNA molecule is ~2.5 nm in width.
- a 2 meter person is 6 feet 6 inches tall or 2 billion nanometers.
What object is the size of a nanometer?
A nanometer is used to measure things that are very small. Atoms and molecules, the smallest pieces of everything around us, are measured in nanometers. For example a water molecule is less than one nanometer. A typical germ is about 1,000 nanometers.
How big is a human hair in nanometers?
between 50,000 and 100,000 nanometres
A human hair is between 50,000 and 100,000 nanometres thick, a single sheet of paper is around 75,000 nanometres thick, while a pinhead is around a million nanometres wide.
What is another name for nanometer?

How will nanotechnology change the world?
In the future, nanotechnology might help us make electrical lines, solar cells, and biofuels more efficient, and make nuclear reactors safer. Nanotechnology might lead to huge advances in health care, improving methods for detecting and treating diseases like cancer.
What is smaller than a nanometre?
Atoms are smaller than a nanometer. One atom measures ~0.1-0.3 nm, depending on the element.
What is above a megameter?
The prefix is mega-, so a megameter is a million meters. Example: 109 is a 1 followed by 9 zeros: 1,000,000,000 (a billion). The prefix is giga-, so a gigameter is a billion meters. It is also called a billionth.
