How to convert megabytes to bytes
Megabytes and Bytes both measure data, so converting is a single multiplication. One MB equals 1,000,000 B, so you multiply your megabytes value by 1,000,000.
Formula: bytes = megabytes × 1,000,000. For example, 10 MB = 10,000,000 B.

Megabytes and Bytes explained
Megabytes (MB): One million bytes, used for photos and documents.
Bytes (B): Eight bits, the basic unit for file sizes.
When you'd convert megabytes to bytes
You'll convert megabytes to bytes whenever a measurement is given in one unit but you need it in the other — comparing megabytes and bytes figures across regions, following a recipe or spec, or double-checking a number. Because 1 MB is exactly 1,000,000 B, the result is precise every time.
Frequently asked questions
How many bytes are in a megabyte?
One MB equals 1,000,000 B. Multiply your megabytes figure by 1,000,000 to get bytes.
What is the formula to convert megabytes to bytes?
bytes = megabytes × 1,000,000. The factor 1,000,000 is exact.
What is 2 megabytes in bytes?
2 MB = 2,000,000 B. You can enter any value in the converter above to get an instant result.
Is this Megabytes to Bytes converter accurate?
Yes. It uses the standard conversion factor (1 MB = 1,000,000 B) defined by IEC 80000-13 — units of information (bit, byte), so results are exact to several decimal places.
