Converting bytes and megabytes
In the conversion tables below, figures are rounded to a maximum of 5 decimal places (7 with smaller numbers) to give approximations.
How many megabytes are there in 1 byte?
There are 1.0E-6 megabytes in 1 byte. To convert from bytes to megabytes, divide your figure by 1000000 .
How many bytes are there in 1 megabyte?
There are 1000000 bytes in 1 megabyte. To convert from megabytes to bytes, multiply your figure by 1000000 .
What is a byte?
It is common for confusion to arise between bytes and bits. A byte represents eight unique bits of information. Each bit will be assigned a value of a 0 or a 1. This entire group of bits will then act as a packet of data. Examples here can be a letter, a number or a symbol such as a question mark. Bytes can be thought of as the "DNA" that is used to form larger strings of data and eventually, entire programs. It is important to keep in mind that unlike the diminutive bit, the byte is used to explain larger numbers.
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).
