It's all about scale!
Micro - very very small! We can start with Bacteria, a single cell organism that is one of the smallest cells alive.
A virus is not a cell (debate on its alive-ness, virus do replicate but do not meet criteria for living organisms, and most scientist think they are not alive!). A virus is very very small - Coronavirus is about 120 nanometers in diameter. Blown up 4000 times, they would be only the size of poppy seeds! A human hair, about 80 micrometers thickness, is many times larger than coronavirus.
Macro - very very large! Let's start with cells making up organisms who live in towns and cities on our Earth (Planet) that revolves around the Sun (a large star) in our solar system, that is in the Milky Way Galaxy, in the local group of galaxies forming a local supercluster of many Galaxies that are part of the very very large Universe! Now we are definitely at a Macro level! And ... our Universe is expanding ...
Our Sun is just one star among hundreds of billions of stars. Our Milky Way galaxy is large, but not as large as many other galaxies like our neighboring Andromeda Galaxy. And there are billions of galaxies in our Universe. Macro scale for sure!

"This illustration, created at the Centers for Disease Control and Prevention (CDC), reveals ultrastructural morphology exhibited by coronaviruses. Note the spikes that adorn the outer surface of the virus, which impart the look of a corona surrounding the virion, when viewed electron microscopically.
