Picometre (American spelling: picometer) is an SI measure of length that is equal to 10−12 of a metre. Its symbol is pm and it is commonly used in measuring atomic-scale distances. Atom diameters are in the range from ~30 to 600 pm.
1 pm = 1 × 10−12 metre
1 pm = 1000 femtometre
100 pm = 1 ångström
1000 pm = 1 nanometre
1 nm = 1000 picometres
