The Difference between a Megabyte (MB) and a Megabit (Mb)

Do you think 1 Megabit per second (1 Mbps) will allow you to download a 1 Megabyte file in one second?

This is not the case. A Megabit is 1/8 as big as a Megabyte.

1 Megabyte = 8 Megabits
Mbps = Megbits per second
MBps = MegBytes per second
Internet speed is usually measured in megabits per second

So, to download a 1MB file in 1 second you would need a connection of 8Mbps ( 8 Megbits per second). The difference between a Gigabyte (GB) and a Gigabit (Gb) is the same, with a Gigabyte being 8 times larger than a Gigabit.

To calculate how long it will take a file to download over your connection, you can use Google’s simple MB/Mb converter:
