So I keep telling people…FWIW file size are always reported in Bytes, and Network speeds should always be repoted in bits. When you represent Gigabyte or Gigabit, it should be B for byte and b for bit, e.g. GB and Gb.
Sometimes it is safer to be explicit regarding the unit, though, writing for example Gbit/s rather than Gbps or Gb/s. We should really adopt the French octet, it would be so much easier differentiating then.
Regarding network speeds, don’t forget that they should always be reported per second.
