How to convert bytes to gigabytes
GB = B × 1×10⁻⁹Multiply the value in bytes by 1×10⁻⁹. To go the other way, multiply by 1,000,000,000 (or divide by 1×10⁻⁹).
A byte is smaller than a gigabyte: it takes 1,000,000,000 bytes to make one gigabyte.

About the units
Byte (B)
Eight bits; the basic addressable unit of memory. One byte equals 8 bits (b).
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 byte?
There are 1×10⁻⁹ gigabytes in one byte, and this value is exact by definition.
How do I convert bytes to gigabytes?
Multiply the number of bytes by 1×10⁻⁹. For example, 10 B × 1×10⁻⁹ = 1×10⁻⁸ GB.
How many bytes are in one gigabyte?
One gigabyte equals 1,000,000,000 bytes. That is the reverse factor, 1 ÷ 1×10⁻⁹.
What is 10 bytes in gigabytes?
10 B = 1×10⁻⁸ 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.
