What Is This Tool?
This tool converts data transfer rates from gigabyte per second, using the SI decimal definition, to an informal unit representing the throughput of a 28.8k dial-up modem. It helps users understand and compare modern fast data transfer speeds with older modem performance.
How to Use This Tool?
-
Enter the data rate value in gigabyte/second (SI definition)
-
Select the output unit as modem (28.8k)
-
Initiate the conversion to see the equivalent modem speed
-
Review examples to understand practical throughput comparisons
-
Use the results to benchmark or understand legacy and modern data rates
Key Features
-
Converts gigabyte/second (SI definition) to modem (28.8k) speeds
-
Uses an exact SI-based gigabyte as 1 × 10⁹ bytes per second
-
Reflects modem 28.8k unit as an approximate analog dial-up data rate
-
Includes illustrative conversion examples for clarity
-
Browser-based and easy to use for quick data rate comparisons
Examples
-
1 Gigabyte/second equals approximately 277,777.78 modem (28.8k) units
-
0.5 Gigabyte/second converts to around 138,888.89 modem (28.8k)
Common Use Cases
-
Comparing contemporary network or storage device data rates with old modem speeds
-
Educating on data throughput differences between modern and historical technologies
-
Benchmarking communication speeds across generations of data transfer methods
Tips & Best Practices
-
Remember modem (28.8k) is an informal and approximate unit for analog dial-up speeds
-
Use SI gigabyte/second for precise high-speed data rate specifications
-
Apply this conversion primarily for comparison and educational contexts
-
Consider technology differences when interpreting conversion results
Limitations
-
The modem (28.8k) unit is informal with inherent variability based on analog telephone technology
-
Gigabyte/second uses exact decimal definitions, so direct equivalence has context restrictions
-
Encoding overheads and differing technologies limit practical one-to-one comparison
Frequently Asked Questions
-
What does gigabyte/second (SI def.) measure?
-
It measures data transfer rate using SI units, defining 1 gigabyte as 1 billion bytes per second.
-
Why use modem (28.8k) as a unit?
-
Modem (28.8k) represents data transfer speeds of classic 28.8 kilobits-per-second dial-up modems, used to compare legacy connection speeds.
-
Is the conversion between these units exact?
-
No, since modem (28.8k) rates are informal and approximate, while gigabyte/second is defined precisely.
Key Terminology
-
Gigabyte/second (SI def.)
-
A data rate unit representing 1 billion bytes transferred each second using the SI decimal system.
-
Modem (28.8k)
-
An informal data rate unit approximating 28.8 kilobits per second throughput of a classic analog dial-up modem.
-
Data transfer rate
-
The amount of digital data moved from one place to another per unit of time.
