About Converting Bits to Gigabits
Bit and Gigabit are everyday digital-storage units, used for everything from file sizes and app downloads to storage device capacity and mobile data allowances. Specifically: Bit digital storage unit, and gigabit digital storage unit.
Formula
gigabits = bits × 1e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 bit equals 1 base unit, and 1 gigabit equals 1000000000 base units, so dividing one by the other gives the direct bit-to-gigabit factor of 1e-9.
Simple example
1 bit × 1e-9 = 1e-9 Gb
1 bit = 1e-9 gigabits.
Real-world example
500 bit × 1e-9 = 5e-7 Gb
500 bits = 5e-7 gigabits.
Conversion table
| Bit (bit) | Gigabit (Gb) |
|---|---|
| 1 bit | 1e-9 Gb |
| 8 bit | 8e-9 Gb |
| 16 bit | 1.6e-8 Gb |
| 64 bit | 6.4e-8 Gb |
| 256 bit | 2.56e-7 Gb |
| 1,000 bit | 0.000001 Gb |
Reverse conversion: Gigabit to Bit
1e-9 Gb × 1000000000 = 1 bit
1e-9 gigabits = 1 bit.
bits = gigabits × 1000000000

Understanding the Bit (bit)
Bit digital storage unit.
Understanding the Gigabit
Gigabit (Gb) measures digital storage/transfer. A gigabit is 1,000 megabits (125 megabytes) under the decimal convention used for network speeds. It is classified as a Decimal (SI-prefixed) digital unit.
Where it's used: Used worldwide for high-speed network ratings (fiber internet, data centers)
Uses of the Gigabit today
- Gigabit fiber internet service advertising
- Data center and enterprise network bandwidth
History of the Gigabit
As internet speeds crossed the 1,000 Mbps threshold with fiber-optic and enterprise networking, 'gigabit' became the standard marketing term for these connections, following the same bits-per-second convention established for slower network speeds.
Historical origin. Gigabit was not the invention of a single named person; it developed through the process described above.
Gigabit — sources
- IEC 80000-13 — Defines bit-based units distinct from byte-based units.

Frequently asked questions
How many gigabits are in 1 bit?
1 bit equals 1e-9 gigabits, using the exact defined conversion factor rather than an estimate.
How do I convert bit to gigabit?
Multiply the bit value by 1e-9. The converter above does this instantly to whatever precision you set.
How do I convert gigabit back to bit?
Use the reverse factor: 1 gigabit equals 1,000,000,000 bits. You can also use the swap control in the converter above to flip the direction instantly.
What is a bit?
Bit (bit) is a unit of digital storage.
What is a gigabit?
Gigabit (Gb) measures digital storage/transfer. A gigabit is 1,000 megabits (125 megabytes) under the decimal convention used for network speeds. It is classified as a Decimal (SI-prefixed) digital unit.
Is the bit to gigabit conversion exact?
Yes. Both bit and gigabit are defined by fixed standards rather than physical artifacts, so the factor of 1e-9 used above is exact to as many digits as you choose to display.
