Converting kilobytes and megabytes
Some commonly asked questions are included below, as well as a reference chart. When making manual conversions, you can use the converter at the top of this page to check your answer.
How many megabytes are there in 1 kilobyte?
There are 0.001 megabytes in 1 kilobyte. To convert from kilobytes to megabytes, multiply your figure by 0.001 (or divide by 1000) .
How many kilobytes are there in 1 megabyte?
There are 1000 kilobytes in 1 megabyte. To convert from megabytes to kilobytes, multiply your figure by 1000 (or divide by 0.001) .
In the chart below, figures are rounded to a maximum of 4 decimal places (6 with smaller numbers) to give approximations.
What is a kilobyte?
As you might have guessed, a kilobyte is commonly defined as consisting of 1,000 bytes. We should point out that its actual value is 1,024 bytes (or 2^10 bytes). Still, most say that this value is very similar to 10^3. It is for this reason that the International System of Units (SI) generally equates the kilobyte with 1,000 bytes. This also helps to somewhat simplify multiplication factors when dealing with such massive numbers. To put this another way, one kilobyte is 10 x 10 x 10 bytes. Although this might seem like a large figure, let's recall that most operating systems contain gigabytes of data capacity!
What is a megabyte?
Most computer users are very familiar with the megabyte. As you might have already guessed, a megabyte is the equivalent of 1,000,000 bytes (or 10^6 bytes). We should point out that there is more than meets the eye here. While the SI definition is one million bytes of information, many computing professionals will instead use the more precise number of 1,048,576 bytes (1,024^2). This arises from the binary multiples that occur (each byte contains eight bits of information within its string).
