In summary, the conversation discusses converting miles to kilometers and the difficulty of finding the right factor when dealing with squared units. It also mentions the periodic table and finding the numbers listed for chromium (Cr).

HInt: The long way from miles to kilometers...
$1\;mile\cdot\dfrac{5280\;ft}{1\;mile}\cdot\dfrac{12\;in}{1\;ft}\cdot\dfrac{2.54\;cm}{1\;in}\cdot\dfrac{1\;m}{100\;cm}\cdot\dfrac{1\;km}{1000\;m}$
Why is your problem any more difficult than this one?
Anyway, you seem to have forgotten that it was SQUARED and you didn't find the right factor.
$1\;\mu m = 10^{-6}\;m$
It's also possible the system is wondering where your units are hiding. $m^{2}$?

We can find the periodic table for instance here: https://www.ptable.com
Which numbers are listed for $\ce{Cr}$?
Related to Help with periodic Table question, express the area in square meters
What is the periodic table?
The periodic table is a tabular arrangement of the chemical elements, organized by their atomic number, electron configuration, and chemical properties.
How do you find the area in square meters?
To find the area in square meters, you need to multiply the length by the width. For example, if you have a rectangle with a length of 4 meters and a width of 3 meters, the area would be 4 x 3 = 12 square meters.
What is the purpose of expressing an area in square meters?
The use of square meters as a unit of measurement for area allows for a standardized and consistent way of comparing the size or extent of different objects or spaces.
How is the periodic table organized?
The periodic table is organized by increasing atomic number, with rows called periods and columns called groups. Elements in the same group share similar properties, while elements in the same period have the same number of electron shells.
What is the importance of the periodic table?
The periodic table is a fundamental tool in chemistry as it provides a visual representation of the elements and their properties. It allows scientists to predict the behavior and characteristics of elements, as well as discover new elements and understand their relationships with other elements.
