100 MB × 1,000,000 = 100,000,000 B.
MB compared with Bytes
One MB is 1,000,000 times as large as one B, so your number gets bigger when you convert MB to bytes and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
About MB and bytes
Megabyte (MB): 1,000,000 bytes. Byte (B): A byte of 8 bits.
Where MB to bytes conversions are used
Drive, phone and cloud-storage sizes are given in gigabytes or terabytes, while operating systems may show gibibytes. File sizes for email, uploads and downloads are quoted in kilobytes and megabytes.
How to calculate MB to Bytes step by step
- Enter the value in MB (the starting unit).
- Multiply by 1,000,000, because 1 MB = 1,000,000 B.
- The product is the value in B. To go back, divide by 1,000,000 or multiply by 0.000001.

Common mistakes when calculating MB to Bytes
- Treating 1 KB as 1,024 bytes: under the SI/IEC convention 1 kB is 1,000 bytes and 1 KiB is 1,024.
- Dividing when you should multiply: from MB to B multiply by 1,000,000; from B to MB divide by 1,000,000.
MB to Bytes FAQ
How many B are in 1 MB?
1 MB equals 1,000,000 B.
How many MB are in 1 B?
1 B equals 0.000001 MB.
Is 1 MB = 1,000,000 B an exact conversion?
Yes. The megabyte and the byte are both defined exactly in SI terms, so the ratio has no measurement uncertainty; 1,000,000 is just that ratio shown to 7 significant figures.
What is a byte (B)?
A byte of 8 bits.
How can I estimate MB to bytes in my head?
One MB is 1,000,000 times as large as one B, so your number gets bigger when you convert MB to bytes and smaller when you convert back. If the answer is not larger than what you typed, you divided instead of multiplying.
What is 150 MB in bytes?
150 MB = 150,000,000 B (since 150 × 1,000,000).
What is 0.5 MB in bytes?
0.5 MB = 500,000 B (since 0.5 × 1,000,000).
