10 Important Difference Between KB And MB (Tabular Form)

Difference between KB and MB
What is the difference between KB and MB?

It is vital to have some understanding of these units of measurement before solving the subject. In a computer, a bit is the smallest unit of data that can be stored in a computer. A bit has only one binary value: 0 or 1. 

A byte, which is made up of 8 bits, is the next unit of measurement in a computer. That is, one byte is equal to 8 bits. 

A byte is a computing unit that represents a character like a letter, number, or typographic sign (for example, “h,” “7,” or “$”). Although bits are the basis upon which data storage is built, bytes are the building elements that truly define the usefulness of any storage system.

In the digital world, the symbols KB, MB, and GB are used to denote units of measurement. They’re most commonly used to describe the size of a digital file or the storage capacity of computers, mobile phones, and other computing equipment. Here, KB stands for kilobyte, MB for megabyte, and GB for gigabyte.

Because bits and bytes were always small units of data measurement, greater units of data are used such as KB, MB, GB, and so on. Below is a table that shows the different types of data storage units from smallest to largest.

What is KB (Kilobyte)?

KB or kB stands for Kilobyte. It is defined as the unit of information or storage capacity in digital electronics. 1 KB is equivalent to 1024 bytes.

A kilobyte, on the other hand, is defined by the International Electrotechnical Commission (IEC) as 1,000 bytes. As a result, the value of one KB could be the same as either of them.

What is MB (Megabyte)?

 MB or mB stands for Megabyte. It is defined as the unit of information or storage capacity in digital electronics. 1 MB is equivalent to 1024 Kilobytes or KB. 1MB is also equal to 1024×1024 (1048576)bytes.

Also, according to IEC, 1MB is equivalent to 1000000 (106) bytes.

What is the key difference between KB  and MB?

Overall, MB and KB are byte-based units of measurement for files. A kilobyte (KB) is 1024 bytes, whereas a megabyte (MB) is 1024 kilobytes. A 1 MB file is 1024 times larger than a 1 KB file.

Is MB bigger than KB?

 Yes, MB is bigger than KB by 1024 times. That means 1MB is equivalent to 1024 Kilobytes. For ease of understanding let us represent KB and MB in terms of bit.

We Know that, Bit is the smallest unit of measurement in digital world. Also a combination of 4 bit is referred to as Nibble and that of of 8 bits is called a byte.

1 Byte = 8 Bit

So, 1 Kilobyte(KB) = 1024 byte = (1024×8)bits = 8192 bits.

Similarly, 1Megabyte(MB) = 1024 KB = (1024×1024) bytes = 1,048,576 bytes = (1048576 x 8) bits =  8,388,608 bits. 

Here we see that by inspection,  8192 >>> 8388608 hence MB is far greater unit of measurement than KB.


In conclusion we learn that KB stands for Kilobyte and MB stands for Megabytes. We can say that MB is a larger unit of measurement than KB as 1 KB of file is equivalent to 1024 bytes while 1MB is equivalent to 1024 KB. Thus, an MB can hold more information than a KB.
