Gigabyte to Bit (GB to bit) Converter
1 gigabyte equals 8,000,000,000 bits — multiply the number of gigabytes by 8,000,000,000 to convert. This uses the decimal (SI) definition where 1 GB = 1,000,000,000 bytes and each byte is 8 bits, so the factor is exactly eight billion.
The formula
To convert gigabytes to bits, multiply by 8,000,000,000:
bit = GB × 8,000,000,000
For example, 2 GB × 8,000,000,000 = 16,000,000,000 bits. To reverse it, divide bits by 8,000,000,000.

How to convert online
These numbers are error-prone by hand, so use the tool:
- Enter your gigabyte value in the first box.
- Read the bit result instantly in the second box.
- Or type a bit value to convert back to gigabytes — it works both ways.

Where this conversion is used
Bits matter whenever storage meets transmission. Network and bandwidth figures are quoted in bits per second, while disks and files are sized in gigabytes, so converting GB to bits lets you estimate transfer times and line capacity. It is also handy in low-level programming and telecom planning.
FAQ
How many bits are in a gigabyte?
One gigabyte equals 8,000,000,000 bits using the decimal definition. Ten GB is 80,000,000,000 bits.
What is the formula to convert gigabytes to bits?
Multiply GB by 8,000,000,000: bit = GB × 8,000,000,000.
How do I convert bits back to gigabytes?
Divide the bit count by 8,000,000,000 (or multiply by 1.25 × 10⁻¹⁰). So 40,000,000,000 bits = 5 GB.
Is the conversion exact?
Yes, under the SI/decimal convention. If your system uses binary gibibytes (1 GiB = 8,589,934,592 bits) the figure differs; this converter uses decimal GB.
