How to Convert Megabytes to Gibibytes (MB to GiB)
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 megabytes into gibibytes by hand, with examples and a quick-reference table.
The conversion
To convert megabytes to gibibytes, multiply the value by 0.0009313226. To go the other way, divide by the same number (or multiply by 1,073.741824). Because the factor is tiny, scientific notation keeps the numbers manageable.
Gibibytes = megabytes × 0.0009313226
Worked examples
- 3 MB = 0.002794 GiB
- 12.5 MB = 0.011642 GiB
- 75 MB = 0.069849 GiB

Common questions
Is MB to GiB exact?
The factors used here are the internationally defined values where they exist; results are rounded for display only.

Mistakes to avoid
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.
Dropping the units
A bare number without a unit is easy to misread later. Always write the unit with the result.
Mixing similar-sounding units
US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.
Background
A conversion table is handy for common values, but a calculator is faster and avoids interpolation errors for anything in between.
Many conversion factors are exact by definition. The inch has been defined as exactly 2.54 centimetres since 1959, and the pound as exactly 0.45359237 kilograms, so conversions involving them can be as precise as you need.
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.
