About Converting Gigabits to Bits
Gigabit and Bit are everyday digital-storage units, used for everything from file sizes and app downloads to storage device capacity and mobile data allowances. Gigabit is most often used for gigabit fiber internet service advertising.
Formula
bits = gigabits × 1000000000
This factor comes from each unit's defined relationship to the category's base unit: 1 gigabit equals 1000000000 base units, and 1 bit equals 1 base unit, so dividing one by the other gives the direct gigabit-to-bit factor of 1000000000.
Simple example
1 Gb × 1000000000 = 1,000,000,000 bit
1 gigabit = 1,000,000,000 bits.
Real-world example
500 Gb × 1000000000 = 500,000,000,000 bit
500 gigabits = 500,000,000,000 bits.
Conversion table
| Gigabit (Gb) | Bit (bit) |
|---|---|
| 1 Gb | 1,000,000,000 bit |
| 8 Gb | 8,000,000,000 bit |
| 16 Gb | 16,000,000,000 bit |
| 64 Gb | 64,000,000,000 bit |
| 256 Gb | 256,000,000,000 bit |
| 1,000 Gb | 1e+12 bit |
Reverse conversion: Bit to Gigabit
1 bit × 1e-9 = 1e-9 Gb
1 bit = 1e-9 gigabits.
gigabits = bits × 1e-9

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.
Understanding the Bit (bit)
Bit digital storage unit.

- IEC 80000-13 — Defines bit-based units distinct from byte-based units.

Frequently asked questions
How many bits are in 1 gigabit?
1 gigabit equals 1,000,000,000 bits, using the exact defined conversion factor rather than an estimate.
How do I convert gigabit to bit?
Multiply the gigabit value by 1000000000. The converter above does this instantly to whatever precision you set.
How do I convert bit back to gigabit?
Use the reverse factor: 1 bit equals 1e-9 gigabits. You can also use the swap control in the converter above to flip the direction instantly.
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.
What is a bit?
Bit (bit) is a unit of digital storage.
Is the gigabit to bit conversion exact?
Yes. Both gigabit and bit are defined by fixed standards rather than physical artifacts, so the factor of 1000000000 used above is exact to as many digits as you choose to display.
Where is the gigabit still used today?
Used worldwide for high-speed network ratings (fiber internet, data centers)
