Bit to Gigabyte Converter (bit to GB)
1 bit equals 0.000000000125 gigabytes (1.25 × 10⁻¹⁰ GB) — multiply bits by 1.25e-10 to convert. Since a gigabyte is 8 billion bits, a single bit is a vanishingly small fraction of one.
The formula
To convert bits to gigabytes, multiply by 1.25 × 10⁻¹⁰:
GB = bits × 0.000000000125
For example, 8,000,000,000 bit × 1.25e-10 = 1 GB. To reverse it, divide by 1.25e-10 (or multiply by 8,000,000,000).

Where this conversion is used
Network throughput and bandwidth caps are often stated in bits, while storage, downloads and data plans are measured in gigabytes. Converting bits to gigabytes helps estimate how long a large transfer takes or how much a stream will consume from a monthly data allowance.
FAQ
How many bits are in a gigabyte?
One gigabyte equals 8,000,000,000 bits (8 billion). So 1 bit is 1/8,000,000,000 GB, or 1.25e-10 GB.
How do I convert gigabytes back to bits?
Divide by 1.25e-10, or multiply by 8,000,000,000. So 1 GB is 8 billion bits.
Is the conversion exact?
Yes, using the decimal (SI) definition where 1 GB = 10⁹ bytes = 8 × 10⁹ bits, giving exactly 1.25e-10 GB per bit.
Is this converter free and private?
Yes. It runs entirely in your browser — nothing is uploaded or stored. It is free, needs no sign-up and works offline once loaded.
