The other N word

The prefix "nano" means one-billionth, or 10^-9; therefore one nanometer is one-billionth of a meter. It’s difficult to imagine just how small that is, so here are some examples:

• A sheet of paper is about 100,000 nanometers thick
• A strand of human DNA  is 2.5 nanometers in diameter
• There are 25,400,000 nanometers in one inch
• A human hair is approximately 80,000- 100,000 nanometers wide
