1. Both megabyte and gigabyte are multiple units of byte used for digital storage and transmission, the difference is in the number of bytes that they consist of. 2. A megabyte contains one million bytes while a gigabyte contains one billion bytes when they are used for computer data storage like hard and flash drives.

The term gigabyte has a standard definition of 10003 bytes, as well as a discouraged meaning of 10243 bytes. The latter binary usage originated as compromise technical jargon for byte multiples that needed to be expressed in a power of 2, but lacked a convenient name.

Actually, it’s both – depending on who you ask. In computers, everything is stored in binary (base 2). So computer engineers used the term gigabyte to denote 1024 megabytes (as well as megabyte for 1024 kilobytes and kilobyte for 1024 bytes), because it was more convenient. …

1 Kilobyte = 1024 bytes. 1 Megabyte = 1024 Kilobytes. It’s complicated. In the International System of Units (SI) “kilo” is defined as 1000, therefore one kilobyte is 1000 bytes.

As the numbers get bigger we start to abbreviate them with k (kilo), m (mega), g (giga), t (tera). The closest base number to a thousand (kilo) is 1024, hence it was abbreviated to k, so 1024 bytes = 1kb.

Here are the most common ones. KB, MB, GB – A kilobyte (KB) is 1,024 bytes. A megabyte (MB) is 1,024 kilobytes. A gigabyte (GB) is 1,024 megabytes.

Answer: Many people think that there are 1000 bytes in a kilobyte. After all, “kilo” means 1000. But there are really 1024 bytes in a kilobyte. The reason for this is because computers are based on the binary system.

In 2018, the total amount of data created, captured, copied and consumed in the world was 33 zettabytes (ZB) – the equivalent of 33 trillion gigabytes. This grew to 59ZB in 2020 and is predicted to reach a mind-boggling 175ZB by 2025.
