# What is the Difference between KB vs. MB

By | December 20, 2021 KB, MB, and GB are the common units of information volume used in computer storage. A bit is the smallest unit of information. It is either a 0 or 1. You can count bits, but it’s not very practical since humans don’t have 10 fingers.

A byte is the next smallest unit and is equal to 8 bits. All other units of information are derived from bits and bytes and represent a certain number of bits (or bytes).

There is a difference between KB and MB and between MB and GB. The following table shows the relationship between these three terms:

1KB = 1,024 bytes = 2^10 = 1024 bytes

1MB = 1,048,576 bytes = 2^20 = 1,048,576 bytes

1GB = 1,073,741,824 bytes = 2^30 = 1,073,741,824 bytes

In simple words, each successive term indicates a tenfold increase in the number of bits or bytes.

KB and MB are quite often used for file sizes. However, even if you’re not a computer geek, there is no way to confuse the two because they are always written as uppercase. And they are never abbreviated (at least not in general use).

There is one exception where these units of measurement get mixed up, though. That is when you’re dealing with processor speeds. For example, a 2 GHz processor can be either 2 GHz or 2.048 GHz depending on context.

In those situations, it’s important to know that 1 GHz = 109 Hz and 1 GHz = 1000 MHz (106 Hz).

But if you’re just looking at a computer file size, don’t worry about this little bit of confusion. You’ll never see KB or MB written as kB or Mb so there’s nothing to worry about there.

KB versus MB. Both of these units are common when talking about storage space or file size. But which is which, and why do they use different abbreviations?

For starters, it’s important to know that a byte (B) is made up of 8 bits (b), and a bit is the smallest unit of computer data. A byte can have a value of either 0 or 1, but both bits together can represent any number from 0 to 255.

The “K” in Kb stands for kilo, which means one thousand. So one kilobyte (KB) is equal to 1,024 bytes, or 2 to the 10th power in base-10 math.

The “M” in Mb stands for mega, which means one million. One megabyte (MB) is equal to 1,048,576 bytes or 2 to the 20th power in base-10 math. To convert between the two units all you need to do is divide by 1,024 or multiply by 1,048,576. For example:

1 MB = 1,048,576 bytes = 2^20 /1024/1024 bytes

1 KB = 1024 bytes = 2^10 /1024/1024 bytes

To convert from KB to MB multiply by 1  This an important chart worth saving during the studies
