How to Convert Bits to Megabytes (bit 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 bits into megabytes by hand, with examples and a quick-reference table.
The conversion
To convert bits to megabytes, multiply the value by 1.250000e-07. To go the other way, divide by the same number (or multiply by 8,000,000). Because the factor is tiny, scientific notation keeps the numbers manageable.
Megabytes = bits × 1.250000e-07
Worked examples
- 3 bit = 3.750000e-7 MB
- 12.5 bit = 1.562500e-6 MB
- 75 bit = 9.375000e-6 MB

Mistakes to avoid
Mixing similar-sounding units
US and imperial gallons, pints and tons are different sizes, and decimal kilobytes differ from binary kibibytes.
Rounding the factor too early
Using 3 instead of 3.28 for feet per metre introduces an error of almost 9% before you have started.
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.
Background
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.
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.
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.
