Answer: The order follows: [tex]1.8\mu g<1.8mg<1.8g<1.8kg[/tex]
Explanation:
Gram is unit which is used to expressed mass of a substance. Many other units can be used to express the mass of a substance. All the units are inter changeable.
For the given values:
Conversion factor from Gram to micro gram
[tex]1\mu g=1\times 10^{-6}g[/tex]
So, [tex]1.8\mu g=1.8\times 10^{-6}g[/tex]
All other units are expressed in this standard unit of mass and then, it will be compared.
Conversion factor from Gram to mili gram
[tex]1mg=0.001g[/tex]
So, [tex]1.8mg=0.0018g[/tex]
Conversion factor from Gram to mili gram
[tex]1kg=1000g[/tex]
So, [tex]1.8kg=1800g[/tex]
Hence, the order follows: [tex]1.8\mu g<1.8mg<1.8g<1.8kg[/tex]
