How to Convert Mebibytes to Bytes (MiB to B)
Data conversions explain why a 1 TB drive shows less space on your computer and help compare mobile plans sold in gigabytes. This guide shows how to convert mebibytes into bytes by hand, with examples and a quick-reference table.
The conversion
To convert mebibytes to bytes, multiply the value by 1,048,576. To go the other way, divide by the same number (or multiply by 9.536743e-07). For a quick estimate, multiply by about 1,000,000.
Bytes = mebibytes × 1,048,576
Worked examples
- 3 MiB = 3,145,728 B
- 12.5 MiB = 13,107,200 B
- 75 MiB = 78,643,200 B

Mistakes to avoid
Multiplying when you should divide
Converting to a smaller unit gives a bigger number, and converting to a larger unit gives a smaller one. If your answer moves the wrong way, you have inverted the factor.
Dropping the units
A bare number without a unit is easy to misread later. Always write the unit with the result.
Forgetting squared and cubed units
Area and volume factors are the length factor squared or cubed, so 1 m² is about 10.76 sq ft, not 3.28.
Background
Unit conversion is simply multiplication by a fixed ratio. The ratio between two units of the same quantity never changes, so once you know it you can convert any value in either direction.
For everyday use, three or four significant figures are usually enough. Engineering, science and trade documents may need more, and rounding should happen only at the end of a calculation.
Writing the units next to every number while you work is the simplest way to avoid mistakes. If the units do not cancel to leave the one you want, the calculation is set up wrongly.
