20 MB equals 20480 KB. This conversion is straightforward because 1 MB is 1024 KB, so multiplying 20 by 1024 gives the total KB.
To convert megabytes (MB) to kilobytes (KB), you multiply the number of MB by 1024 since each MB contains 1024 KB. For example, 20 MB times 1024 results in 20 x 1024 = 20480 KB, which is the total kilobytes in 20 megabytes.

Conversion Formula
The formula for converting MB to KB is simple: multiply the number of megabytes by 1024 because there are 1024 kilobytes in a megabyte. For instance, if you have 10 MB, multiplying 10 x 1024 gives 10240 KB. This works because of the binary measurement system used in computing.
Conversion Example
- Convert 5 MB to KB:
- Step 1: Recognize the conversion factor is 1024 KB per MB.
- Step 2: Multiply 5 by 1024.
- Step 3: 5 x 1024 = 5120 KB.
- Convert 15 MB to KB:
- Step 1: Use the conversion factor 1024 KB per MB.
- Step 2: Multiply 15 by 1024.
- Step 3: 15 x 1024 = 15360 KB.
- Convert 0.5 MB to KB:
- Step 1: Recognize 0.5 MB equals half a megabyte.
- Step 2: Multiply 0.5 by 1024.
- Step 3: 0.5 x 1024 = 512 KB.
- Convert 25 MB to KB:
- Step 1: Use the conversion factor 1024 KB per MB.

Conversion Definitions
mb
MB stands for megabyte, a unit of digital information storage. One MB equals 1024 kilobytes, used primarily in measuring file size, storage capacity, and data transfer rates in computing devices and digital media.
kb
KB is short for kilobyte, a data measurement unit representing 1024 bytes. It is used to quantify small file sizes, document sizes, and memory in computer systems, especially when data amounts are less than a megabyte.
Conversion FAQs
How many KB are in 20 MB?
Since 1 MB equals 1024 KB, 20 MB equals 20 x 1024 = 20480 KB. This is calculated by multiplying the megabyte value by 1024, the standard number of kilobytes in a megabyte, based on binary system conventions.
Can I convert MB to KB without a calculator?
Yes, because the conversion involves multiplication by 1024, which is straightforward if you recognize that 1024 is 2^10. For quick estimates, you can think of 20 MB as approximately 20,000 KB, but for precise value, multiply by 1024.
Why is the conversion factor 1024 instead of 1000?
Because computers operate using binary, where data sizes are based on powers of two, 1 MB equals 1024 KB instead of 1000 KB, which is used in decimal-based measurements like storage devices’ marketing terms.
What is the difference between MB and GB?
MB (megabyte) is 1024 KB, while GB (gigabyte) is 1024 MB. So, 1 GB equals 1024 x 1024 = 1,048,576 KB, making GB a larger unit used to measure bigger data sizes like hard drive capacity.
Is 20 MB the same as 20,000 KB?
Not exactly. 20 MB is 20 x 1024 KB, which equals 20,480 KB, slightly more than 20,000 KB due to the binary conversion system. This difference is important for precise data calculations.
