Based on the standard conversion rate of 1 GB/s = 55.2336329218 STM-1.
Supports telecom industry and network engineering applications.
Browser-based and easy to use with clear input and output fields.

Examples

Convert 1 GB/s to STM-1: results in approximately 55.2336 STM-1 units.
Convert 2 GB/s to STM-1: equals about 110.4673 STM-1 units.

Common Use Cases

Translating high-level data transfer rates for telecom backbone link planning.
Aggregating lower-rate telecom channels into SDH systems.
Integrating computing data throughput measurements with telecom SDH or SONET infrastructures.
Analyzing storage and network operation speeds relative to telecom link capacities.

Tips & Best Practices

Clarify whether gigabytes follow SI (10^9 bytes) or binary (2^30 bytes) definitions before converting.
Understand that STM-1’s fixed bit rate limits precise byte-rate granularity.
Consider network protocol overheads separately as they are not covered by this conversion.
Use the tool primarily for telecom backbone and network engineering contexts.

Limitations

Assumes gigabyte as SI unit (1 GB = 10^9 bytes), so binary gigabytes (GiB) yield different results.
STM-1 has a fixed bit rate of 155.52 Mbit/s, limiting granularity compared to continuous byte rates.
Does not account for protocol overhead, error correction, or line coding effects on throughput.
