Nano Bits

Nano is from the Greek word for “dwarf”; it indicates one-billionth of something.

Nanotechnology is the creation and use of objects at the nanoscale, up to 100 nanometers in size.

1 nanometer (1nm) = 1/1,000,000,000 of a meter (close to 1/1,000,000,000 of a yard).

1 human hair is ~50,000 nanometers across; or 50 nanometers is one-thousandth the width of a human hair.

1 bacterial cell measures a few hundred nanometers across.

The smallest things seeable with the naked eye are 10,000 nanometers.

1 nanometer = 10 hydrogen atoms in a line.


When you are dealing with units that are LARGER than a meter you multiply by the appropriate factor.

When you are dealing with units that are SMALLER than a meter you multiply.

Below is a chart that shows what happens every time you multiply and divide by a thousand.

So basically if you move up the chart you multiply and if you move down the chart you divide.
