Answer
$1.54\ \dot{A}$
$154\ pm$
$1.54\times10^{-10}\ m$
Work Step by Step
In angstroms:
$0.154\ nm\times \dfrac{1\times10^{-9}\ m}{1\ nm}\times \dfrac{1\ \dot{A}}{1\times10^{-10}\ m}=1.54\ \dot{A}$
In picometers:
$0.154\ nm\times \dfrac{1\times10^{-9}\ m}{1\ nm}\times \dfrac{1\ pm}{1\times10^{-12}\ m}=154\ pm$
In meters:
$0.154\ nm\times \dfrac{1\times10^{-9}\ m}{1\ nm}=1.54\times10^{-10}\ m$
