In 1 gigabytes there are 8,000,000,000 bits. Meanwhile in 1 bits there are 1.25000e-10 gigabytes. Keep reading to learn more about each unit of measure and how they are calculated. Or just use the Bits to Gigabytes calculator above to convert any number.

To convert gigabytes (GB) to bits (b), use these two facts:
Conversion formula (GB to bits):
bits = gigabytes × 1,000,000,000 × 8
That means:
Tip: Don’t mix up GB and Gb. GB means gigabytes, while Gb means gigabits.
It depends on the type of gigabyte you mean.
Most storage makers use decimal GB. Many computer systems report sizes closer to binary.
Use this simple formula:
If you use decimal units:
If you use binary units:
A byte holds 8 bits. Gigabytes are based on bytes, not bits.
So you convert gigabytes to bytes first, then multiply by 8 to get bits.
No. They use different base systems.
That difference adds up, especially with large files and drives.
Using decimal GB (common for drive labels and many data plans):
Using binary units (2 GiB):
Using decimal GB:
Using binary units (10 GiB):
Using decimal GB:
Using binary units (100 GiB):
No, and the case matters.
Also, 1 GB = 8 Gb (in decimal terms). People mix these up a lot with internet speed and file size.
File sizes often use GB, while internet speeds often use bits per second (bps).
To convert a file size to bits:
To estimate download time, you also need your connection speed in bps and any overhead. Real-world speeds often run lower than the label.
Storage makers often use decimal units (GB). Operating systems often use binary math, even if they still display “GB.”
Example:
The bits conversion changes too, depending on which unit you start with.
Use decimal GB when you deal with:
Use binary GiB when you deal with:
If you’re not sure, check the context and the label (GB vs GiB).
These are the most common errors:
Getting the unit right first saves time later.
The Calculate Box tool to convert gigabytes to bits uses the open source script Convert.js to convert units of measurement. To use this tool, simply type a gigabytes value in the box and have it instantly converted to bits.
