how many bytes = 1 KB? how many KB = 1 MB? and how many MB?

8 Bits = 1 Byte

1024 Bytes = 1 KiloByte

1024 KiloBytes = 1 MegaByte

1024 MegaBytes = 1 GigaByte

1024 GigaBytes = 1 TeraByte

Bytes To Mb

This is going to get crazy.

- Kilobyte Wiki

"When referring to data transfer rates and hard disk drive storage size, "kilobyte" means 1000 (10^3) bytes. On the other hand, random-access memory capacity such as CPU cache measurements are always stated in multiples of 1024 (2^10) bytes, due to memory's binary addressing."

- Above is an example of what usually confuses people.

There is another system with prefixes ending in 'bi' e.g. kibi 2^10, being used for binary whereas the other is used for decimal.

And now for some conversions to show where the 'bi' comes in:

8 bits = 1 byte

1000 bytes = 1 megabyte

1000 megabytes = 1 gigabyte

1000 gigabytes = 1 terabyte

1000 bits = 1 kilobit

1000 kilobits = 1 megabit

1000 megabits = 1 gigabit

1000 gigabits = 1 terabit

1024 bytes = 1 kibibyte

1024 kibibytes = 1 mebibyte

1024 mebibytes = 1 gibibyte

1024 gibibytes = 1 tebibyte

1024 bits = 1 kibibit

1024 kibibits = 1 mebibit

1024 mebibits = 1 gibibit

1024 gibibits = 1 tebibit

If you're still reading, I hope this helps you.

If you think I'm wrong please tell me why, I just want the correct answer.

1024 KiB kibibyte KB kilobyte

10242 MiB mebibyte MB megabyte

1024x3 GiB gibibyte GB gigabyte

1024x4 TiB tebibyte –

1024x5 PiB pebibyte –

1024x6 EiB exbibyte –

1 Byte = 8 bits

1024 Bytes = 1 KiloByte

1024 KiloBytes = 1 MegaByte

1024 MegaBytes = 1 GigaByte

1024 GigaBytes = 1 TeraByte

I am very disappointed to see that out of 5 answers, 4 were incorrect, and the correct answer is not on the top.

As Ryan said, kilo(k), mega(M), giga(G) are always powers of 10. So they are multipliers of 1000.

kibi(Ki), mibi(Mi), gibi(Gi) are powers of 2. So they are multipliers of 1024.

Depending on what are you referring to, you may want one or the other.

Memory (as in RAM) is measured in powers of 2. So a RAM card could have 1GiB (one gibibytes or 1024 mibibytes) or 512MiB.

Storage doesn't need to be in powers of 2, so it can be human friendly power or 10. So a file could have 10GB (10 gigabyes, 10 000 megabytes)

Network speeds also don't need to be powers of 2. But they are usually measured in bites per second.

So Ethernet has a speed of 10 or 100 or 1000 megabites per second. A speed of 8megabits per second can also be called a speed of 1megabyte per second.

There is nothing wrong in saying a speed of 1Gibibits (meaning 1024 Mibibits, meaning 1024*1024*1024*1024 bits) but it would be needlessly confusing.

Hope this helps.

Data transfer rate is the rate that a certain amount of data is transferred over a given period in time. An example would be when you download something online. While downloading you see the progress bar and the Data Transfer rate (i.e. Kilobytes per second KB/s

1024 Bytes = 1 KiloByte (KB)

1024 KiloBytes (KB) = 1 MegaByte (MB)

1024 MegaBytes (MB) = 1 GigaByte (GB)

1024 GigaBytes (GB) = 1 TeraByte (TB)

I don't know how some compute a kilobyte as 11024. A kilobyte is 1024 or 2 (binary) to the 11th power.

why 1kb is equal to 1024 bytes

11024 Bytes = 1 KiloByte (KB)

1024 KiloBytes (KB) = 1 MegaByte (MB)

1024 MegaBytes (MB) = 1 GigaByte (GB)

1024 GigaBytes (GB) = 1 TeraByte (TB)000
