Traffic Consumed in GB or MB

Hello hello, I'm new here.
I bought a new router NR5101, so far it's working great.
Good at capturing networks, wifi very good.
But my question or doubt, I want to know how much m

obile data I have already consumed.
No, it's very clear.
It presents in bytes and is very confusing.
You can improve this problem.
In fact, I think mobile data consumption should be on the home page...
