21 MB to kB

Do you want to change 21 MB to kB? If so you have come to the right page. Here we have 21 MB in kB and all you want to know about 21 megabytes in kilobytes. If you have been looking for how many Kb in 21 MB or 21 Mbps to kbps then you are right here, too. Note that in 21 MB to kB the letter k is always lowercase and means kilo, whereas the letter B is spelled uppercase, so that MB means megabytes, in contrast to Mb, b lowercase, which stands for megabits, usually eight times less than one MB. Read on below to learn all about 21 MB in kB.

Convert 21 MB to kB

To convert 21 MB to kB we have to multiply the amount in megabytes (MB) by 1000 to get the equivalent in kilobytes (kB). The formula is [kB] = [21] * 1000. Sometimes MByte is used in place of the symbol MB, and the occasionally used term kByte means kB. Therefore, for bytes we get:

21 MB = 21000 kB
21 MByte = 21000 kByte
21 Megabytes = 21000 Kilobytes

In bits: 21 Mb to kb = 21000 kb (kilobits), and here you can convert 21 kB to MB.

In digital storage, 21 megabytes equal 21000 kB. 21 MB = 21 * 1000 B. If you want to convert another amount of digital information, then use our MB to kB converter below. If you like you can also convert 21 mebibytes (MiB) to kibibytes (KiB), known as binary prefixed multiples of byte. 1 MiB = 1024 * 1024 B.

21 MB to kB usually means 21 megabytes to kilobytes, but the use of digital storage units and symbols is inconsistent among main memory, disk drives, information transfer rates and clock speed for example. By definition, what is 21 MB in kB is clear, yet some vendors are not following international standards. For more details see the concluding paragraph of this post.

21 Mbps to kbps

Here we explain data transfer rates, not capacity or storage. 21 Mbps to kbps refers to data transfer rates in multiples of bits, not bytes. The data rate unit Mbps indicates the average number of symbols or characters in million bits transmitted per second. For megabits per second to kilobits per second we have this equation: 21 Mbps = 21000 kbps.

21 MBps to kBps is less common in download speed and upload speed. The capitalized letter B tells us that we are converting multiples of bytes, blocks of information usually consisting of 8 bits, from MBps to kBps, which is from megabytes per second to kilobytes per second. Applying the constant mega to kilo ratio of 1000:1 we get 21 MBps = 21000 KBps.

21 MB in kB

If you have been asking yourself is 21 MB smaller than 21 KB, then the answer in any case is “no”. If, on the other hand, you have been wondering is 21 MB bigger than 21 kB, then you now know that this is indeed the case.


To sum 21 MB in kB up:

The answer to the question how much kB in 21 MB is usually 21000 kB, but depending on the vendor of the RAM, hard disk, the software producer or the CPU manufacturer for example, MB could also mean 1024 * 1024 B = 10242 bytes. Even a mixed use 1000 * 1024 B cannot completely ruled out. Unless indicated differently, go with 21 MB equal 21000 kB.

21 MB to kB

As opposed to storage or capacity, data transfer rates measure how fast information is transmitted from one location to another. 21 Mbps in kbps equals 21000 kilobit per second and 21 MBps in kBps is equivalent to 21000 kilobyte per second.
