A
unit of spatial measurement that equals one-billionth (10 -9) of a meter. The
head of a pin is about 1 million nanometers across. A human hair is about
60,000 nanometers in diameter, while a DNA molecule
is between 2-12 nanometers wide.
One
billionth of a meter; approximately the length of three to six atoms placed side-by-side, or the width of a single
strand of DNA; the thickness of a human hair is between 50,000 and 100,000
nanometers.
