Example conversion table
This example shows typical conversions between gigabits and gigabytes, with their decimal and binary storage equivalents rounded to four decimal places.
| Gigabits (Gb) | Gigabytes (GB) | Megabytes (MB, decimal) | Terabytes (TB, decimal) | Gibibytes (GiB, binary) | Mebibytes (MiB, binary) |
|---|---|---|---|---|---|
| 1 | 0.1250 | 125.0000 | 0.0001 | 0.1164 | 119.2093 |
| 10 | 1.2500 | 1250.0000 | 0.0013 | 1.1642 | 1192.0929 |
| 50 | 6.2500 | 6250.0000 | 0.0063 | 5.8208 | 5960.4645 |
| 100 | 12.5000 | 12500.0000 | 0.0125 | 11.6415 | 11920.9290 |
Formula used
The converter uses standard relationships between bits, bytes, and larger units in both decimal (SI) and binary (IEC) systems.
- 1 byte = 8 bits
- 1 gigabit (Gb, decimal) = 109 bits
- 1 gigabyte (GB, decimal) = 109 bytes
- Gigabytes (decimal) from gigabits: GB = Gb ÷ 8
- Megabytes (decimal): MB = GB × 1000
- Terabytes (decimal): TB = GB ÷ 1000
- 1 gibibyte (GiB) = 230 bytes
- GiB from gigabits: GiB = (Gb × 109) ÷ (8 × 230)
- Mebibytes (MiB): MiB = GiB × 1024
When you switch the direction to gigabytes to gigabits, the inverse relationship is used: Gb = GB × 8.
How to use this calculator
- Enter one or more values in the input area.
- Choose whether the numbers represent gigabits or gigabytes using the conversion direction dropdown.
- Set the number of decimal places to control rounding of all displayed outputs.
- Decide whether to show binary storage equivalents (GiB and MiB) in the results table.
- Click the Convert button to generate the table.
- Use the CSV button to download a spreadsheet-friendly file of all the results.
- Use the PDF button to capture a printable summary of the current results table.
Example of using this calculator
Suppose you want to know how many gigabytes 80 gigabits represent when planning a data transfer.
- Type 80 in the input values box.
- Keep the direction set to Gigabits → Gigabytes.
- Choose an appropriate number of decimal places, for example four.
- Click the Convert button.
The table will show 80 Gb equals 10 GB, 10000 MB, 0.01 TB, and about 9.3132 GiB or 9536.7432 MiB, depending on your selected precision.
Related concepts and calculators
Understanding bits, bytes, and data rates
Network links are usually specified in bits per second, while storage is quoted in bytes. This converter helps you align both views by transforming gigabits into gigabytes for capacity and throughput comparisons in a single, consistent table.
Planning download times and transfer windows
When estimating download times, you often receive file sizes in gigabytes but bandwidth in gigabits per second. Converting between them lets you estimate how long large backups, media deliveries, or database replications will take under real network conditions.
Decimal versus binary capacity metrics
Storage vendors quote decimal gigabytes, while operating systems often report binary gibibytes. By showing GB, GiB, MB, and MiB together, this tool clarifies why the same device can appear to offer different capacities in different interfaces.
Combining unit conversions across disciplines
Engineering tasks frequently mix data rates with physical units. For example, you can pair this tool with the PSI to GPM converter when designing systems that monitor both fluid flow and sensor data streaming over a network.
Relating runtime metrics to distance and usage
Equipment dashboards sometimes present readings in unusual units. You might combine runtime tools, such as converting operating hours to equivalent usage metrics, with this gigabits to gigabytes calculator to estimate how much telemetry data continuous monitoring will create over those intervals.
Linking to other data conversion tools
Your workflow may involve several conversion stages. Use this gigabits to gigabytes calculator alongside other tools from your conversion section, such as those translating between pressure and flow or between different data rate units for integrated engineering or networking projects.
Frequently asked questions
What is the difference between gigabits and gigabytes?
One gigabit is one billion bits, while one gigabyte is one billion bytes. Because there are eight bits in a byte, one gigabyte equals eight gigabits in the decimal system used by most network and storage vendors today.
When should I use each conversion direction?
This tool converts in both directions. Choose Gigabits → Gigabytes when you start from a bandwidth figure such as a link capacity. Choose Gigabytes → Gigabits when your starting point is a file size or storage requirement.
Does this calculator use decimal or binary prefixes?
No. This calculator uses decimal prefixes, where one gigabit is one billion bits and one gigabyte is one billion bytes. For binary prefixes like gibibytes, the tool shows GiB and MiB separately so you can compare capacities accurately.
Can I convert multiple values at once?
Yes. Paste multiple values separated by commas, semicolons, or new lines into the input area. The converter parses every valid number, ignores blanks, and builds one summary table so you can export everything together as CSV or PDF.
What should I check if my results seem incorrect?
If the results look wrong, first check the conversion direction. Then confirm that your numbers use the units you expect, and review the decimal places setting. Finally, verify whether you are comparing decimal gigabytes to binary gibibytes in another tool.
When should I export results as CSV versus PDF?
CSV export is ideal when you want to open the table in spreadsheet software, sort or filter rows, or combine conversions with other datasets. PDF export is better for sharing a static, printable record in reports or email attachments.
How many decimal places should I use for conversions?
Use decimal values when link speeds or file sizes come from vendor datasheets, operating systems, or browsers, because they almost always use decimal prefixes. Use more decimal places when you need to compare close capacities or avoid rounding errors.
