Gigabytes to Bits Converter
How to convert gigabytes to bits
bits = gigabytes × 8,000,000,000
To convert gigabytes to bits, multiply the number of gigabytes by 8,000,000,000.
1 GB = 8,000,000,000 bit
Examples
- 500 GB × 8,000,000,000 = 4,000,000,000,000 bit
- 64 GB × 8,000,000,000 = 512,000,000,000 bit
Good to know
Decimal (SI) unit based on powers of 1000, as used by drive manufacturers. Windows reports sizes in binary units (powers of 1024) but labels them "KB", "MB", "GB" and "TB", so the same file or drive shows a smaller number there.
8 bits make 1 byte. Bits (lowercase b) and bytes (uppercase B) are easily confused in abbreviations such as Mb and MB.
