Bits to GB Converter

How to convert bits to gigabytes

FormulaGB = b × 1.25×10⁻¹⁰

Multiply the value in bits by 1.25×10⁻¹⁰. To go the other way, multiply by 8,000,000,000 (or divide by 1.25×10⁻¹⁰).

A bit is smaller than a gigabyte: it takes 8,000,000,000 bits to make one gigabyte.

About the units

Bit (b)

A single binary digit, 0 or 1.

Gigabyte (GB)

10⁹ bytes. Phone storage, data plans and RAM are sold in GB. One gigabyte equals 8,000,000,000 bits (b).

Frequently asked questions

How many gigabytes are in one bit?

There are 1.25×10⁻¹⁰ gigabytes in one bit, and this value is exact by definition.

How do I convert bits to gigabytes?

Multiply the number of bits by 1.25×10⁻¹⁰. For example, 10 b × 1.25×10⁻¹⁰ = 1.25×10⁻⁹ GB.

How many bits are in one gigabyte?

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

What is 10 bits in gigabytes?

10 b = 1.25×10⁻⁹ GB.

Is this b to GB 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.
