About this calculator

GB is 10^9 bytes (decimal), how drives are sold. This converter turns any value in GB into 7 other data units at once, using fixed conversion factors. Targets include B (one byte, eight bits); KB (1,000 bytes (decimal)); MB (1,000,000 bytes (decimal)).

How it works

Every result equals your value in GB multiplied by a constant. For example, 1 GB = 1,000,000,000 B and 1 GB = 0.93132 GiB.

Worked example

Convert 5 GB: that is 5,000,000,000 B and 4.6566 GiB.

Common mistakes

• Mixing decimal (GB) with binary (GiB) units.
• Confusing bits with bytes when reading network speeds.
• Check the unit symbol: GB is 10^9 bytes (decimal), how drives are sold, so confirm your source uses that same definition.
