$1\text{nm}$ is equivalent to

A nanometer ($\text{nm}$) and an Angstrom ($\text{A˚}$) are units of length defined as:
* $1\text{nm}=10^{-9}\text{m}$
* $1\text{A˚}=10^{-10}\text{m}$

To convert nanometers to Angstroms, we compute the ratio:

$$\frac{1\text{nm}}{1\text{A˚}}=\frac{10^{-9}\text{m}}{10^{-10}\text{m}}=10$$

Therefore, $1\text{nm}=10\text{A˚}$.
