Convert Bits per Second to Gigabits per Second - Data Transfer Converter
This converter converts data transfer rates expressed in bits per second (bps) into gigabits per second (Gbps) using the SI (decimal) definition of the prefix Giga = 10^9. It is intended for engineering, network planning, and measurement tasks where standard decimal prefixes are expected.
By default the tool uses the decimal (SI) relationship: 1 Gbps = 1,000,000,000 bps. For contexts that require binary prefixes (Gibibit, GiB) the converter includes notes and alternative formulas showing the 2^30 relationship used by IEC/ISO standards.

Methodology
The conversion applies the International System of Units (SI) decimal prefix 'Giga' which equals 10^9. This is the convention used by networking standards, many vendors, and official metrology guidance.
When users require a binary-prefix alternative, the IEC standard defines 'gibi' (Gi) where 1 Gibit = 2^30 bits ≈ 1,073,741,824 bits. We provide both forms so you can confirm results against measurement devices or documentation that use binary prefixes.
Practical note for measurements: instrument reporting, firmware rounding, or packet-overhead can cause reported throughput to differ from theoretical conversions. For traceable calibration and test-method guidance consult NIST and FCC recommendations referenced below.
Worked examples
1,000,000,000 bps → 1 Gbps (decimal)
10,000,000 bps → 0.01 Gbps
1,073,741,824 bps → 1 Gibit/s (1 Gibps, binary definition ≈ 1.0737 Gbps decimal)
125,000,000 bytes per second → 1 Gbps (125,000,000 B/s × 8 = 1,000,000,000 bps)
F.A.Q.
What's the exact relationship between bps and Gbps?
Using SI (decimal) prefixes: 1 Gbps = 1,000,000,000 bps (10^9). For binary-prefix contexts, 1 gibibit per second (Gibps) = 2^30 bits = 1,073,741,824 bps.
When should I use decimal Gbps vs binary Gibps?
Use decimal Gbps (10^9) for networking specifications, service-level agreements, and most vendor documentation. Use binary Gibps (2^30) only when the documentation or measurement system explicitly references IEC binary prefixes (Gi).
How do I convert bits to bytes and relate GB/s to Gbps?
There are 8 bits in a byte. To convert bps to bytes per second, divide by 8. To convert gigabytes per second (GB/s, decimal) to gigabits per second (Gbps), multiply GB/s by 8 (1 GB/s = 8 Gbps, decimal).
Why might my measured throughput not match the converted number?
Real-world throughput differs due to protocol overhead (headers, acknowledgements), link-layer framing, device CPU limits, and measurement tool rounding. Also check whether the tool reports decimal or binary prefixes and whether it reports line-rate vs payload rate.
Are there authoritative references for these conversions?
Yes. The National Institute of Standards and Technology (NIST) documents SI prefixes and recommended usage; the IEC and ISO set binary-prefix standards. See the citation list for direct references.
How should I report results for regulatory or procurement documents?
Report the unit system you used (decimal vs binary) and include the conversion factor. For procurement and compliance, follow the specific regulatory or contract wording; many agencies and vendors expect SI/decimal prefixes.
Do measurement instruments need calibration for data-rate tests?
Yes. For repeatable, traceable measurements, use calibrated test equipment and documented test procedures. NIST and FCC provide guidance on test methodologies and traceability for communications measurements.

Assumptions & limitations
- Uses exact unit definitions from the Fidamen conversion library.
- Internal calculations use double precision; display rounding follows the unit's configured decimal places.
- Not a substitute for calibrated instruments in regulated contexts.
- Jurisdiction-specific rules may require official guidance.
