How to Convert Gibibytes to Bits (GiB to bit)
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 gibibytes into bits by hand, with examples and a quick-reference table.
The conversion
To convert gibibytes to bits, multiply the value by 8.589935e+09. To go the other way, divide by the same number (or multiply by 1.164153e-10). For a quick estimate, multiply by about 8,600,000,000.
Bits = gibibytes × 8.589935e+09
Worked examples
- 3 GiB = 25,769,803,776 bit
- 12.5 GiB = 107,374,182,400 bit
- 75 GiB = 644,245,094,400 bit

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

Mistakes to avoid
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.
Dropping the units
A bare number without a unit is easy to misread later. Always write the unit with the result.
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
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.
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.
A conversion table is handy for common values, but a calculator is faster and avoids interpolation errors for anything in between.
