Frequently asked questions

How many bits are in one gigabyte?

There are 8,000,000,000 bits in one gigabyte, and this value is exact by definition.

How do I convert gigabytes to bits?

Multiply the number of gigabytes by 8,000,000,000. For example, 10 GB × 8,000,000,000 = 80,000,000,000 b.

How many gigabytes are in one bit?

One bit equals 1.25×10⁻¹⁰ gigabytes. That is the reverse factor, 1 ÷ 8,000,000,000.

What is 10 gigabytes in bits?

10 GB = 80,000,000,000 b.

Is this GB to b converter accurate?

Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
