Answer: The value in milligram per square millimeter is \(14.2mg/mm^2\)
Explanation:
We are given a value of \(1.42g/cm^2\)
To convert this value into milligrams per square millimeters, we use the conversion factor:
1 g = 1000 mg
\(1cm^2=100mm^2\)
Converting the above speed into miles per hour, we get:
\(\Rightarrow (\frac{1.42g}{cm^2})\times (\frac{1000mg}{1g})\times (\frac{1cm^2}{100mm^2})\\\\\Rightarrow 14.2mg/mm^2\)
Hence, the value in milligram per square millimeter is \(14.2mg/mm^2\)
