Bits to Gigabytes Converter
How to convert bits to gigabytes
gigabytes = bits ÷ 8,000,000,000
To convert bits to gigabytes, divide the number of bits by 8,000,000,000.
1 bit = 1.25 × 10⁻¹⁰ GB
Examples
- One byte: 8 bit ÷ 8,000,000,000 = 1 × 10⁻⁹ GB
- 64 bit ÷ 8,000,000,000 = 8 × 10⁻⁹ GB
Good to know
8 bits make 1 byte. Bits (lowercase b) and bytes (uppercase B) are easily confused in abbreviations such as Mb and MB.
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.
