One nanometer (nm) is equal to one billionth of a meter, or 0.000000001m.

A picometer (pm) is one trillionth (millionth of a millionth) of a meter, or 0.000000000001m.
A femtometer (fm) is one quadrillionth (millionth of a billionth) of a meter, or 0.000000000000001m.
And so on and so forth, dividing by one thousand each time:
Attometer (am) = quintillionth of a meter
Zeptometer (zm) = sextillionth of a meter
Yoctometer (ym) = septillionth of a meter
Eventually, there's the Planck length, widely considered to be the smallest mesure of distance, equal to about 1.6 x 10-35m.

Don't worry I didn't write this.
