Answer
$7.5\times10^{-6}\ m$
$7500\ nm$
$7,500,000\ pm$
Work Step by Step
In meters:
$7.5\ \mu m\times\dfrac{1\times10^{-6}\ m}{1\ \mu m} = 7.5\times10^{-6}\ m$
In nanometers:
$7.5\times10^{-6}\ m\times\dfrac{1\ nm}{1\times10^{-9}\ m}=7500\ nm$
In picometers:
$7.5\times10^{-6}\ m\times\dfrac{1\ pm}{1\times10^{-12}\ m}=7,500,000\ pm$
