how many bits are in a byte ?

bit (b)
1 byte (B) = 8 bits
1 Kilobyte (K / KB) = 10^3 bytes = 1,000 bytes
1 Megabyte (M / MB) = 10^6 bytes = 1,000,000 bytes
1 Gigabyte (G / GB) = 10^9 bytes = 1,000,000,000 bytes
1 Terabyte (T / TB) = 10^12 bytes = 1,000,000,000,000 byte

1 Megabyte = 1,024,000 bytes.

There are 1,000 KB (Kilo Bytes) in on MB (MegaByte)
There are 1,000 MB in one GB (GigaByte)
