How many 5 GB in MB

"5 000 Mega" Wrong.
There are 8bits to a byte. 1024bytes to a kilobyte. Kilo representing one thousand.
There are 1024kb (kilobytes) in 1Mb (Megabyte). Mega representing 1 million.
Therefore there are 5120Mb (Megabytes) in 5Gb (Gigabytes). Giga representing 1 billion. 1024Gb (Gigabytes) in 1 Tb (Terabytes). Terra representing 1 trillion bytes.
Bits and Bytes, 1's and 0's. Binary, or on and off.
