Nanometer is a very small unit of length, equal to one hundredth of a meter. In other words, one meter equals 100 million nanometers. A centimeter is a slightly larger unit of length, equal to one hundredth of a meter.

So one nanometer is equal to 0.0000000 1 cm. This means that a nanometer is only one billionth of the length of a centimeter. This ratio is very small and unimaginable. If we enlarge one nanometer to the same proportion as basketball, then basketball will become as big as the earth, and one nanometer will become a small ball. Nanometer is a very important unit because it can be used to describe very small things, such as molecules, cells and atoms.

Nanometer application

1, electronic equipment

The performance of electronic devices manufactured by nanotechnology is much better than that of traditional electronic devices, and the power consumption can also be greatly reduced. There is a lot of information storage. On a 5-inch CD less than the size of the palm of your hand, you can store all the books of at least 30 Beijing libraries.

2. Pottery

Nanoceramics are both rigid and flexible. Nano-ceramics are plastics made of nano-ceramic particle powder, which has brought a revolution to the ceramic industry. When nano-ceramics are applied to engines, cars will run faster and planes will fly higher.

3. Oxides

The colored nano-oxide particles of nano-oxide materials can quickly change color under the irradiation of light or the action of electric field. As a soldier, it is very good to protect the glasses of the laser gun. Billboards made of nano-oxide materials will become more colorful under the action of electricity and light.
