Megabyte (MB)
A decimal megabyte (MB) is exactly 1,000,000 bytes (1,000 KB) — not to be confused with the binary mebibyte (MiB).
Decimal MB sizes photo attachments, app downloads, and cloud storage tiers on many consumer devices.

How to convert
Exact conversion factors in both directions, plus a worked example.
1 MB = 1000000 B
1 B = 0.000001 MB
To convert megabyte to byte, multiply by 1000000.
To convert byte to megabyte, multiply by 0.000001.
Example: convert 10 MB to B
10 × 1000000 = 10000000 B
About these units
Short background on the units used in this conversion.
Byte (B)
A byte is 8 bits — the standard unit for file sizes, RAM, and storage capacity in computing.
Bytes and their multiples describe hard drives, downloads, and memory on phones and computers.
Frequently asked questions
How many bytes are in one megabyte?
One megabyte equals 1,000,000 bytes. Multiply your megabytes value by 1,000,000 to convert to bytes.
What is the conversion formula?
B = MB × 1,000,000The reverse is
MB = B × 0.000001, using the same exact factors as this converter.Is this Megabyte to Byte converter private?
Yes. All calculations run locally in your browser. Nothing you type is sent to a server.
