Nanometre - Wikipedia

The nanometre (international spelling as used by the International Bureau of Weights and Measures; SI symbol: nm) or nanometer (American spelling) is a unit of length in the International System of Units (SI), equal to one billionth (short scale) of a metre (0.000000001 m) and to 1000 picometres. One nanometre can be expressed in scientific notation as 1×10 m, and as 1/1000000000 metres. WebBulk Aqueous Hybrid Liquid Membrane (BAHLM) Processes with Water-Soluble Carriers. Vladimir S.
