A "Nano" is a Greek term meaning a billionth. So, a billion nanometers (nm) would be equal to one meter. Refer to http://en.wikipedia.org/wiki/Nanometer Since a nano is such a small size, hence the term: Nanotechnology which stands for microscopic sized machines.
Nanometer is definitely smaller then a meter.
A nanometer is 10^-9 meter, whereas a micrometer is 10^-6 meter. So a nanometer is 1000th of a micrometer. A nanometer is smaller.
A nanometer is (1/1,000,000,000) of a meter, you decide
1 nanometer=1.0510-9
That would be a nanometer.
A nanometer is 1×10−9 meters, or 0.0000000001 meters.
micron is bigger than nanometer. millianth part of meter is micron and billianth part of meter is nanometer.
Nanometer is 10-9 meter, in other words, a unit of length.
A nanometer is one billionth of a meter or 1 X 10-9 meters.
