dude yeah its a nano
there really is no cut off
but in my opinion i would say the cut off is at 30G

< 5 = pico
5 - 20 = nano
20 - 40 = small
40 - 90 = average
> 90 = large

I just made those up. I don't think it matters what the definitions are. In reality, anything smaller than the ocean is really a nano.
