bit/byte and kilo/mega/giga/tera/peta

Convention:
“b” (small B) denotes bit and “B” (capital B) denotes byte.
128 kb = 128 kilo bit
16 kB = 16 kilo byte
For some cases, “k” (small K) before “b” denotes bit and “K” (capital K) denotes byte.
128 kb = 128 kilo bit
16 Kb = 16 kilo byte
So,
1 Kilo Byte = 1 kB = 1 KB
1 Kilo Bit = 1 kb
Learning:
1 Byte = 8 Bit
1 kb (Kilo-Byte)
= 1000 bit
= 125 Byte
= 0.125 KB

1 mb (Mega-Bit)
= 1000 kb
= 1000 x 1000 bit
= 125,000 Byte
= 125.00 KB
= 0.125 MB

1 gb (Giga-Bit)
= 1000 mb
= 1000 x 1000 kb
= 1000 x1000 x1000 bit
= 125,000,000 Byte
= 125,000 KB
= 125 MB
= 0.125 GB
