A nano meter is: 1x10^-9 meters in scientific notation.
Or it can alternatively be written as: 0.000000001 meters.
In other words it is tiny!
It can alternatively be looked at a one billionth of a meter!
To put a nanometer in perspective think about this stuff:
A milimeter is about the same thickness as a toe nail.
Now, there are 1million nanometers in a millimeter. So, your toe nail is about 1million nanometers thick!
Now consider this cool fact regarding nano scale engineering: Computer chips have circuitry that is 1 nanometer thick. The entire Bible could be printed on a computer chip the size of a postage stamp. Amazing!

There are 0.000000001 meters in a nanometer.
1 nanometre equals one billionth (10-9) of a metre.
A nanometer is 1×10−9 meters, or 0.0000000001 meters.
There are 1 billion nanometers in a meter. Therefore, 100 nanometers is equivalent to 0.0000001 meters.
1 nanometer = 10^-9 meter 1 micron = 10^-6 meter Number of microns in 1 nanometer = (10^-9)/(10^-6) = 1/1000
