1 nm is equal to

1 nanometer (nm) is equal to 1×10−91\times 10^{-9}1×10−9 meters (m). This means one nanometer is one billionth of a meter. It can also be expressed as 10 angstroms (Å), where 1 Å = 10−1010^{-10}10−10 meters. So:

• 1 nm = 1×10−91\times 10^{-9}1×10−9 m
• 1 nm = 10 Å

This is the standard conversion used in science and engineering for length measurements at the nanoscale.
