Bits and Byte Prefixes

Nibble = 4 bits
x2 Nibbles = 1 byte = 8 bits
Kb= Kilobit = 1000 bits = 125 bytes
Mb = Megabit = 1,000,000 bits

KB = Kilobyte = 10^3 = 1000 bytes
MB = Megabyte = 10^6 = 1,000,000 bytes
GB = Gigabyte = 10^9 = 1000 MB
TB= Terabyte = 10^12 = 1000 GB

Ki (KiB) = Kibibyte = 2^10 = 1024 bytes
Mi (MiB) = Mebibyte = 2^20 = 1,048,576
Gi (GiB) = Gibibyte = 2^30 = 1024 Mi
Ti (TiB) = Tebibyte = 2^40 = 1024 Gi
