I'm getting more confused.
Asking those who are more knowledgeable if my understanding of the terminology is correct:
kilobyte = kB (or kByte)
kilobit = kb (or kbit)
megabyte = MB (or MByte)
megabit = Mb (or Mbit)1 megabyte = 1000 kilobyte = 8 megabit = 8000 kilobit
1 megabit = 1000 kilobit = 0,125 megabyte = 125 kilobyteIf you consider the relatively modern terminology of using base-10, yes, but the traditional computing science units that I was taught some 30 years ago are:
1 Megabyte = 1024 Kilobytes
The use of base-10, rather than base-8 numbers is a relatively new concept - you'll see some references to SI-sounding unit names like kibibit and kibibyte and mebibit and mebibyte. These terms didn't exist when most of us oldies were going through school/college/university.
It's why your 2TB hard drive is actually 1.85TB in reality - disk drive manufacturers always use the base-10 version to make it seem larger.
That's why gigabit (1000 megabit) ethernet has a maximum transfer rate of ~125 megabytes/sec (1000 / 8 = 125).
Oh yes, I knew about this. It doesn't help my general confusion about the units that the kibi- is abbreviated with a capital K ("Kibit"). 😅
