How to Convert Megabytes to Terabytes (MB to TB)
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 terabytes by hand, with examples and a quick-reference table.
The conversion
To convert megabytes to terabytes, multiply the value by 1.000000e-06. To go the other way, divide by the same number (or multiply by 1,000,000). Because the factor is tiny, scientific notation keeps the numbers manageable.
Terabytes = megabytes × 1.000000e-06
Worked examples
- 3 MB = 3.000000e-6 TB
- 12.5 MB = 1.250000e-5 TB
- 75 MB = 7.500000e-5 TB

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.
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.
Singapore adopted the metric system in the 1970s, replacing imperial units and traditional Chinese measures in most official uses. Metric units are now standard in schools, trade and government, but older units survive in property, markets and imported goods.
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.
