Not trying to discourage discussion here, but this might be best suited for a tech sub as the logic that led to the decisons is still valid. Anyone with good knowledge of programming should be able to answer.

More common in what?

Internet, for instance, has been sold in kilobits and megabits per second.

Is your question more to do with how the general public measures or how industry measures?
