The same thing can be said about car fluids. They all come in quart containers that can look similar. If you don't pay close attention to the container and read the labels, then you maybe putting brake fluid in for oil, transmission fluid in for power steering, etc. Hell I have actually seen a guy put Diesel gasoline in his unleaded pickup truck, because he didn't look closely at the pump, but had no problem pumping 20+ gallons of it and then have to pay for it
I'm just trying to say that your original post was saying that the units of measure are confusing, when units of measure are just that, units of measure nothing else. Now if the luser does not understand what the units actually measure then that is a totally different topic then this one and is most likely a little easier for most technologists to cope with. GB's, MB's, MHz's. These are not units of measures that are typically taught to the masses.
Kind of like electricians getting testy over people confusing amps and voltage.
