How small is 7 nanometers?

What is 7-nanometer? When used in relation to stuff like CPUs and video cards the term 7-nanometer refers to the size of the transistors involved. The smaller the transistor the more you can fit onto a piece of silicon and the more powerful and complex that the components built from these transistors are able to be.

Is nanometer bigger than Picometer?

Yes: the prefix “nano” indicates a quantity of 10^(-9). In this case a nanometer is 10^(-9) meters. By contrast the prefix “pico” indicates a quantity of 10^(-12). A picometer is 10^(-12) meters ie 1000 times smaller.
