megabyte to byte - How to convert MB to B
From word documents to high-resolution images, digital files are measured in bytes. But most people are more familiar with megabytes. The megabyte to byte conversion shows how one common unit expands into millions of the smallest building blocks of storage.
What is a megabyte (MB)?
A megabyte (MB) equals 1 000 000 bytes in decimal or 1 048 576 bytes in binary. MBs are widely used to describe file sizes, app downloads, and photos.
What is a byte (B)?
A byte (B) is made of 8 bits and represents a single character, number, or symbol. Bytes are the foundation of all digital storage and communication.
Conversion formula
The formula for MB to B is straightforward:
Byte (B) = Megabyte (MB) × 1 000 000
Example:10 MB × 1 000 000 = 10 000 000 B

Do you know?
-
A short text document is usually under 50 KB, equal to about 50 000 bytes — a fraction of a single MB.
-
A digital photo at high resolution can easily be 5 MB, or 5 million bytes.
-
A standard CD-ROM holds around 700 MB, equal to 700 million bytes.
From Bytes to MB and Back Again
The relationship between bytes and megabytes has been at the core of digital progress. In the early computing days, memory was counted in bytes or kilobytes. Simple programs and games often had to fit into less than 64 KB.
By the 1990s, as files and applications grew larger, megabytes became the new benchmark. Software, music, and eventually video files required millions of bytes to store and share. CDs popularized MB-scale storage, letting users carry hundreds of files on a single disc.
Today, while we talk in gigabytes or terabytes, the underlying math still comes back to MB and bytes. Every photo you take, every app you install, and every file you download is ultimately measured in bytes, grouped into MB for convenience.

MB to B: The Core of Digital Files
The megabyte to byte conversion reminds us that modern storage rests on small, simple units. Each MB contains a million bytes, and each byte can represent just a single character or number.
From simple documents to complex multimedia, this bridge explains how small building blocks scale into the files and systems we use daily.
