How to Convert Terabytes to Megabytes (TB to MB)
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 terabytes into megabytes by hand, with examples and a quick-reference table.
The conversion
To convert terabytes to megabytes, multiply the value by 1,000,000. To go the other way, divide by the same number (or multiply by 1.000000e-06). For a quick estimate, multiply by about 1,000,000.
Megabytes = terabytes × 1,000,000
Worked examples
- 3 TB = 3,000,000 MB
- 12.5 TB = 12,500,000 MB
- 75 TB = 75,000,000 MB

Common questions
Is TB to MB 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.
Mixing similar-sounding units
US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.
Dropping the units
A bare number without a unit is easy to misread later. Always write the unit with the result.
Background
A conversion table is handy for common values, but a calculator is faster and avoids interpolation errors for anything in between.
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.
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.
