Gigabytes to bits converter
Bits (b)
1 gigabyte = 8,000,000,000 bits
How to convert gigabytes to bits
b = GB × 8000000000
Multiply the number of gigabytes by 8000000000 to get bits. Going the other way, divide by 8000000000 (or multiply by 1.25 × 10^-10).
One gigabyte is exactly defined as 8000000000 bits (to 12 significant figures), and one bit is 1.25 × 10^-10 gigabytes.
Worked examples
- Convert 5 gigabytes: 5 × 8000000000 = 40,000,000,000 40,000,000,000 bits.
- Convert 12.5 gigabytes: 12.5 × 8000000000 = 100,000,000,000 100,000,000,000 bits.
- Convert 250 gigabytes: 250 × 8000000000 = 2,000,000,000,000 2,000,000,000,000 bits.
